# Do Light Waves Require a Medium?

Many people wonder whether light waves require a medium in order to be propagated. The answer is yes. The wave of light is electromagnetic radiation and, as a result, requires a medium to propagate. As space is filled with electrons and positrons, light travels through it at a lower speed than the other waves. However, under certain conditions, electrons can be detected and absorbed. This is the reason why there is no need to use a medium for light to travel.

Light waves travel through space without a medium. The restoring force is made up of electromagnetic forces and electrical charges. This is what makes light energy accessible to humans. Magnetic forces attract magnets and electric charges attract each other. When light is propagated through a medium, it is converted to heat and moved back to the source. This process is called photoelectric conversion. While sound waves are electromagnetic in nature, they need a medium to transmit their energy.

Unlike sound and mechanical waves, light waves do not require a medium to propagate. Instead, they need a medium in order to be able to travel through space. Fortunately, light does not need a material medium to move through space, but a medium is still needed to propagate through it. In fact, a light wave can travel through a vacuum at a speed of 186,000 meters per second.

## Do Light Waves Require a Medium to Travel?

Light is a wave that travels in a vacuum. But like sound and water, it requires a medium to travel. Its electromagnetic nature makes it impossible to propagate through the air. In 1801, Thomas Young demonstrated that light is a wave by passing a beam of light through a series of parallel slits. He observed that alternating dark and bright bands appeared on a white screen. Since light is a wave, there is no medium in which to propagate it.

The frequency of light depends on its polarization, but EM waves do not need a medium. Because they are transverse, they travel without a medium. They are characterized by a pair of oscillating fields. These transverse waves propagate in the opposite direction of their propagation direction. They do not require a material medium to travel. This is because electromagnetic waves do not rely on a physical medium to transmit them.

The speed of light is constant. Therefore, it does not need a medium to travel. As long as the speed of light is equal to the speed of light, it can travel through an empty space. However, EM waves do not need a medium to propagate. In fact, light can even travel through solid materials or empty space without a medium. This fact is a great help to the understanding of electromagnetic waves.

## Can Light Travel Without a Medium?

It is possible for light to travel without a medium. Most waves require a medium to propagate, such as air, to make them. However, light is a different type of wave that does not need a media to travel. This type of wave consists of packets of energy called photons, which are tiny particles that travel through space more rapidly and lose less energy than other kinds of waves.

The speed of light traveling through a vacuum is 299,792,458 meters per second (983,571,056 feet per second). The speed of light is known as the universal constant, “c.” Mechanical waves require a medium to transmit energy to other parts of the world, while electromagnetic waves do not. Sound and water waves need a medium to travel. The difference between a radio wave and a light wave is that they do not need a carrier medium to propagate.

The speed of light does not depend on the medium. Because it is a transverse wave, it can pass through a vacuum at a rate of 186,000 miles per second. Its magnetic and electric fields help it travel through a vacuum, and they don’t dissipate when they travel through a vacuum. This makes them very effective at transmitting information. But why would light need a medium at all?

## Does Light Need a Medium to Travel?

The double-slit experiment proved that light can behave as individual particles or as a wave. Its speed of travel through space is independent of the direction it is traveling. Unlike sound waves, which require a medium to travel, lightwaves are unaffected by the medium in which they travel. They can move freely through space. In the end, there is no need for a medium for light to travel.

Because light is a wave, it does not need a medium to travel. Its speed is constant and experimentally determinable, which makes it a perfect medium for communication. Similarly, sound waves and radio waves do not require a material medium to propagate. However, light can travel through solids, air, and water, which may slow down its speed. Consequently, it is not possible to see how light works without a medium.

Light waves can travel without a medium. This is because they behave as transverse waves and do not dissipate in an empty space. Therefore, it is not necessary for a medium to be present for light to travel. Because of this property, light does not require a physical medium to travel. It is capable of traveling at the speed of light and not be affected by any material. So, do light waves need a media?

## Is Light Mechanical?

If you’ve ever driven on a train track, you may have noticed that the tracks rattle when the train moves. This is because the vibrations of the train cause the metal tracks to move. As the metal particles bounce off of each other, the vibrations of the trains cause mechanical waves to propagate. When these waves travel through a solid material, they travel at a high speed. By contrast, when they travel through an empty space, they only travel at a low speed.

Mechanical waves propagate through a medium until all the energy is transferred. In contrast, electromagnetic waves require no medium to travel and have no mass. When the displacement of a mechanical wave is larger than its wavelength, it has a chaotic or nonlinear effect. For example, if a woman moves a toy spring, the wave will propagate away from her. She will disturb the toy spring in a vertical direction, resulting in a transverse wave.

Light waves do not involve motion of matter and can travel through a vacuum. Sound waves and water waves are examples of mechanical waves. Both types of waves are similar to slinky or stadium waves, although light is different from them. In addition, they do not involve a medium and do not require a physical object to propagate. These are not the same as the sound wave, but both can be considered electromagnetic waves. If you’ve been wondering if light is mechanical, consider the following:

## Do Light and Gravitational Waves Require a Medium for Propagation?

Do light and gravitational waves require a medium for propagation? In fact, all waves do not require a medium for propagation. In fact, the electromagnetic wave theory has no requirements at all. The reason for this is that any source of light can be regarded as a signal, and its properties are similar to that of sound. Then, why does light need a physical medium? To answer this question, we need to consider the different kinds of signals that travel through our world.

Light and sound need a material medium for propagation, but electromagnetic waves do not. Because they do not need a material medium, they can travel through a vacuum. In fact, electromagnetic waves do not need a physical medium at all. They can even pass through a vacuum. They do not need a material medium for propagation. Moreover, they are not disturbances of the material world. Instead, they are vibrations of electric fields, known as electromagnetic fields. In other words, they can travel as fast as light.

Although sound and light need a physical medium for propagation, electromagnetic waves do not. They travel without a material medium. They do not depend on the properties of a medium to travel. Rather, they are vibrations of electromagnetic fields that exist everywhere. Unlike sound and mechanical waves, they do not have a physical medium. Because of this, they can travel through a vacuum. Therefore, it is important to understand the difference between light and sound.

## What is Light Ray and Light Beam?

The most basic difference between light ray and light beam is the way they move. A ray is a single stream of light energy, while a beam is a collection of rays that trace a path. This article will discuss the differences between a light ring and a light ray. Read on to learn about their differences and how they differ from each other. Let’s get started!

First, we should understand the difference between a ray and a beam. A ray is a straight line in which light moves, while a beam is a group of light rays. A ray is a single stream of energy; a beam is a collection of rays that travel at the same speed. A beam can be either convergent or divergent, or can be any of the two.

A light ray is a path or entity that carries energy through space. A beam, on the other hand, is a group of similar rays that move in a single direction. While both types of rays are similar, they hold different meanings. An arrow represents an arrow, while a beam represents a straight line with an arc. Therefore, a ray is a single, unidirectional strand of electromagnetic energy, and a beam is a collection of radiated energy.

## Do Light Waves Require a Medium?

The Michaelson-Morely experiment was one of the first attempts to find this mysterious medium. Scientists observed the speed of light passing through empty space. They were looking for ether. But they didn’t find it. Instead, they discovered that there was no medium at all. So, the Michaelson-Morely experiment failed. And we’re left wondering: Is there a medium that makes light waves travel?

All waves have a common property: they travel through a medium. The medium in which a sound wave travels is air. Meanwhile, the components of a light wave and transverse waves oscillate perpendicularly. This means that light and mechanical waves cannot propagate through an empty space without a medium. But in practice, the electromagnetic fields are so powerful that they can travel through anything. So, do light waves need a media? Yes, they do.

The restoring force of light is well understood. It consists of magnetic and electric forces. These forces are what cause electricity to flow through wires. The magnetic force is what makes magnets attract. So, what’s the difference? It’s the medium that carries the wave from its source to its destination. Whether it’s the ocean or a violin string, the disturbance travels through the medium.

## How Does Light Travel?

How does light travel? It’s a classic physics mystery that hasn’t been solved to this day. It is a wave, which means that it has no medium through which it can move. This allows light to propagate freely and is the basis of wave mechanics. Here are some ways to describe light. Here are a few of the more common explanations: a spherical particle, a cylinder, or a beam of rays.

In a nutshell, light travels from its source to its destination. The speed of light varies based on its energy. It travels faster or slower in different mediums, such as air, water, or air. It is a transverse wave, and has no mass. Because it doesn’t have a mass, it can move through different materials. It’s the only substance in our world that can slow down light.

Light travels in one of three ways: directly through empty space, through a medium, or through a solid. It can also be transverse, or traverse a medium. The medium is not an obstacle to light, but it affects the speed of light. It can also pass through solids, and can bend and distort. Regardless of its medium, light travels at an incredible speed.

## How Do Light Waves Travel?

In order to move from one place to another, light travels in waves. Unlike other waves, light does not require a medium to move from one place to another. Each wave consists of many parallel rays. Each ray has its own wavelength. The wavelength of a wave is the distance between the corresponding points on each successive wave. A ray’s wavelength can be measured from any point on the wave. The greater the wavelength, the more energy is emitted by the light.

Light waves can travel with or without a medium. While they can travel through a vacuum, light can only move through a medium that is uniform in density. In the absence of a solid medium, light can move through a vacuum. It is this property of light that allows it to travel in straight lines. Regardless of the medium, light will bend in the direction of the direction it is traveling.

The speed of light depends on the type of medium that it travels through. The medium can be air, water, or a vacuum. In either case, it will always propagate. Since light is transverse, it does not need a medium to move. Regardless of its medium, it must travel through a uniform medium in order to move. The wave will not move if it does not have a uniform background.

## What Kind of Wave Is Light Transverse Or Longitudinal?

A light wave is composed of two components – an electric field and a magnetic field. These two components oscillate perpendicular to the direction of propagation. In a normal wave, the two components do not move, but instead oscillate back and forth about their equilibrium point. This is known as a transverse or longitudinal waves. These waves are not curved, so they are not considered to be waves.

The electromagnetic wave is made up of three components: transverse waves and longitudinal waves. In a transverse wave, the displacement of the medium is perpendicular to the direction of propagation. In a longitudinal wave, the medium moves in a direction parallel to the direction of propagation. Photons carry the visible light. Other forms of electromagnetic radiation are also carried by photons, making light a wave.

Light is an electromagnetic wave and has both longitudinal and transverse properties. Its characteristics make it different from other waves in nature, such as sound and soundwaves. For example, a transverse wave has particles traveling parallel to the path of propagation, while a longitudinal wave has particles traveling in a perpendicular direction. However, the two types of waves have some differences. If you are interested in learning more about the properties of light, read on!

## Can Light Waves Travel With and Without a Medium?

When light waves travel, they don’t need a medium to carry energy. For example, a rock thrown in a pond creates waves. Meanwhile, light consists of tiny particles known as photons that travel through space like particles. However, the difference between them is that light passes through a medium at a faster rate and loses less energy than a particle does.

A medium is the only thing that can slow down the speed of light. A uniform medium can contain particles and molecules, which are different from light. The density of a solid can also affect the speed of light, so it is not possible to travel faster than the density of a liquid. A thin film of oil or water will also dampen the speed of light, so it will travel slower. If a solid is in the way, the wave will get refracted and bend.

Light waves move as transverse waves. This means that they can move through a solid, and through a vacuum, which makes them faster. Since light has both a magnetic and an electric field, it can travel without a medium, and it can move through solids. It does not need a medium in order to travel through space. The speed of light is the same for any type of wave.

## How Does Light and Sound Travel in Waves?

How do light and sound travel in waves? These are scalar phenomena, which means that both can only travel in the form of a wave when they have a medium through which they can be propagated. Sound is a form of mechanical energy, caused by the vibration of matter, whereas light is an electromagnetic force. This makes both forms of waves different, but there are some similarities. In general, both forms travel at the same speed and can only be detected when the medium through which they are travelling is completely empty.

The same principles apply to sound and light. The difference between light and sound is the type of medium that the waves travel through. When a sound wave is traveling through air, it always needs a medium. The speed of the sound will depend on the type of medium used. When a fast-moving object hits an air molecule, the air molecules bounce around, disrupting the direction of the movement. This movement is referred to as a pressure wave.

Light and sound are energy-based waves. They move through an air medium at varying speeds. They have different wavelengths and can travel at a speed up to one million miles per second. The difference between light and sound is most obvious when you compare light and sound. However, they have one thing in common: they both travel at the speed of light. And that is the difference between them.

## How Does Light Travel From Its Source?

Light travels in straight lines, but how does it get bent? Several factors contribute to the bend of light, including refraction and reflection. This article looks at how light is bent. It can also explain how a camera works. For a basic understanding of how light moves, read on! Listed below are three ways that light can bend. You can play flashlight tag to demonstrate one way that light can travel through a card.

First of all, light comes from nothing. If this were true, then the speed of light would never change. When the speed of light is reduced, the distance that light travels is called the wavelength. Likewise, if it traveled at a fixed rate, the wavelength of light will increase. However, the distance that a wave moves can be affected by various mediums. Only gravity can stop light from traveling through a space, so that it can interact with another object.

The third way that light travels is through media. It can move through empty space, air, glass, and mirrors, among others. Geometric optics deals with the ray aspect of light. In this way, light can travel through a variety of media, including a lens. The speed of light is a major factor in the movement of light. If we could model light‘s path through media, we could better understand how it moves through space.

## How Does Light Travel in a Uniform Medium?

In a uniform medium, light waves travel in straight lines. This is a constant. Its ray angle is the angle between the surface, interface, and line normal to the surface. Light is a wave that moves as transverse waves. It can travel through a vacuum at an astonishing speed of 186,000 miles per second. It has an electric and magnetic field. The rays of light are always moving in a straight line.

In a uniform medium, light travels as a wave, traveling at a constant speed. There is no material that impedes the passage of light, so light can move through a vacuum or airless space. It is a perfect example of a wave’s physics. It does not need a medium to travel. It can move through an airless space. In a vacuum, however, the light is completely free of any matter and can travel through anything.

In a medium that is not uniform, light propagates along a straight path. A wave is defined as an ellipsoid. It does not need any material to travel. It can pass through airless space or a vacuum. A uniform medium, such as a black hole or a clear sky, will not prevent light from reaching the earth. It does not matter what the material is.

## How Do Radio Waves Travel Without a Medium?

It is a widely known fact that radio waves can travel through any medium, including vacuums. However, they can also travel through static materials. Magnetic and electric fields in a vacuum are induced by a moving object. This changes the state of the field and causes electromagnetic waves to form. As radio waves are invisible, they do not require a medium to propagate. Heinrich Hertz used Maxwell’s theory to produce radio waves.

Although a material medium is needed for sound waves to travel, a vacuum is a perfect medium. Air is made of molecules, and it cannot transmit sound waves. By contrast, radio waves travel at the speed of light. Therefore, they are classified as an electromagnetic wave. Unlike light, radio waves can travel in any environment because they are invisible. A material that has a higher density is a good medium for radio waves.

Radio waves travel through a vacuum with little loss. They are very small, with energy values of 10-22 to 10-30 joules. The process is considered a continuous, classical process, governed by Maxwell’s equations. The speed of radio waves is the same as light, and the speed of light is nearly identical in air and other thin materials. A material that impedes a radio signal is not a good medium for radio waves.

## What is Light Wave Medium?

Light waves travel through a medium. The space around us is filled with positrons and electrons, and these particles are the medium through which light can travel. Though these particles are normally undetectable, they are able to detect each other under extreme conditions. Scientists are working on ways to determine what these unusual materials are and how they can influence the way light behaves. They may help us better understand how the universe works.

The electromagnetic waves, like light, do not require a medium to travel. They can be transmitted through the vacuum of space. However, in order to be able to travel further, light needs a medium to carry its disturbance. A wave medium can be anything from air to violin strings to spring toys. A wave can pass through an indefinite number of mediums and still remain unobstructed. In fact, a solid can actually act as a medium for light.

Light may travel through any medium. It can be thought of as a stream of photons or a form of electromagnetic waves. There are no physical limits on the length of a light wave. In fact, it can travel through the void of space. A light wave can be either transverse or longitudinal. Its properties are different from those of sound or radio waves, which do not have a medium. For example, light travels through solids like water and air.

## What Line Does Light Travel?

Light travels in a straight line, but it can change direction when it encounters an obstacle. This phenomenon is known as diffraction. In a transparent medium, light is unobstructed and travels in a straight line. The wave-like nature of light gives it properties of both particles and waves. Photons, or packets of energy, are a small subset of these two classes.

Light can travel in any direction, but it must pass through a solid object to reach its destination. Hence, it must be traveling in a straight line. Opaque objects cannot let light pass. Moreover, photons do not travel in a straight line. They travel in waves, which change direction when they cross a boundary. Unlike spherical waves, they do not have any trajectories.

As electromagnetic waves, light moves in a straight line, unless the object that it encounters is opaque. In that case, it cannot pass through an opaque object. Nevertheless, light waves do not travel in a straight line, which is another characteristic of quantum particles. Moreover, unlike classical particles, photons do not have trajectories. Unlike spherical waves, these tiny entities do not propagate in a single direction. Therefore, light waves do not follow a straight path.

The speed of light depends on its wavelength. The wavelength of light is the distance between two peaks of the wave. The amplitude is the height of the peak. Hence, the higher the amplitude, the greater is the speed of light. It is the speed of light that determines the length of an object. When it moves through a material, such as air, it travels a straight line.

## How Does Light Travel?

Did you know that light travels at 186,282 miles per second? That means it would take a space shuttle 37,200 years to travel the distance of a light-year. Using the same formula, you can calculate how far light will go in a year. In fact, light is so fast that it can travel as far as a planet from Earth. A light-year is about 9 trillion kilometers or 6.78 trillion miles.

If you are wondering how far light travels, the answer is simple. It’s actually made up of waves. Transverse waves are like ripples in a tank of water. The direction of the vibration is 90 degrees opposite to the direction in which light travels. That means that light can travel in straight lines as well. This means that it moves more slowly through materials like water, glass, and air. The speed of light is the same for all these materials, but it can take longer to reach the point where it’s blocked.

Light moves at the speed of light. A wave has the same direction as the motion of a particle. The wave’s velocity is 180 degrees opposite to the direction of travel, and the light follows that same direction. Therefore, a wave can’t travel faster than light. So, a photon traveling at 186,000 miles per second travels at about 9.5 million miles per second. The distance between Earth and another star, Proximasad Centauri, is 4.23 light years. The distance between Earth and the star is a few hundred million miles and billions of kilometers.

## Why Does Light Travel Slower in a Medium?

A medium slows down the speed of light by interacting with it. This process occurs because charged particles interact with photons, which are uncharged. The more charges a medium has, the slower the speed of light will be. But a charge is not what causes light to travel slower. The interaction between photons and charged particles results in a delay in the speed of light. It is important to understand why the interaction occurs and how it affects light‘s speed.

A material’s refractive index determines the speed of light. A material’s refractive index, or RI, will determine the speed of light. If a material has a high refractive index, the light will travel at a slower speed. A material with a low refractive indices is opaque. In addition, a medium’s refractive index can decrease or increase the speed of light.

This reduction in speed is caused by a change in phase velocity. This change in velocity results in the physical effects of refraction. The material’s refractive index is the ratio of c and the phase velocity. The resulting difference is called the refractive index. Although the refractive index of a material can be high, the fact that light travels slowly is attributed to a drastic reduction in the group velocity of light, not abnormally high refractive indices.

## What Happens When Light Rays Travel Through a Medium?

What happens to light rays as they travel through a medium? – This is a question that has captivated scientists for centuries. This answer to this question is as simple as it is fascinating: waves of light travel in a straight line, and a group of them coming from the source of light is a beam. Both sound and light waves are electromagnetic, and they can travel in a vacuum. The differences between the two types of waves lie in their origins and how they interact with one another.

Light waves are inherently circular, and they travel in straight lines. This means that they can’t curve around corners. That’s why an opaque object blocks light and makes a shadow on its other side. Photons are energy that travel in the form of particles called photons. Whenever they reach a material, they impact the atoms of that material. Metal atoms absorb the energy from the light and become opaque, whereas glass atomic structure allows light to pass through.

Light travels as a wave, which means that it doesn’t need matter to carry its energy. This property makes it possible for light to pass through airless space. In fact, light can even travel through vacuum at 186,400 miles per second. When passing through a medium, the waves bend toward their normal direction. A denser substance will make light travel slower. So, the next time you’re stuck trying to figure out what happens to light when it passes through a medium, remember to bring a flashlight!

## The Difference Between Electromagnetic and Mechanical Waves

There are many similarities and differences between electromagnetic waves and mechanical waves. Although they are both produced by the vibration of charged particles, the differences are based on their properties. As the difference between the two waves is vast, it may seem difficult to distinguish between them. Light is the most common example of an electromagnetic wave, while sound is the most common example of a mechanical wave. Let’s look at how they differ.

Mechanical waves travel through a medium, whereas electromagnetic waves require a medium to travel. Think of the ripples in a pond: these are examples of mechanical waves. When the two are in conflict, they are referred to as “electromagnetic radiation.” In fact, these two types of radiation are not identical. If one is affected by the other, it will affect the other wave as well.

Mechanical waves travel through a medium, while electromagnetic waves do not. Their characteristics are different, and their propagation speeds are different. For example, an alternating magnetic field will affect electromagnetic waves differently from a steady magnetic field. The difference between the two is that electromagnetic waves travel through a material and are called “elastic.” A physical medium is necessary to carry mechanical waves, so that they can move.

## How Light Waves Travel in a Uniform Medium

Light waves travel in straight lines in a uniform medium, varying in wavelength only. These waveforms are composed of charged particles that traverse a path. Each wave’s length depends on its frequency and energy. The speed of light depends on its intensity. The faster the rate of sound, the higher its frequency. Regardless of the speed, light is always in a uniform state.

The wavelength of a light wave varies as it moves through a medium. Transverse waves are perpendicular to a plane, vibrating parallel to a line (Ad), while longitudinal waves are at right angles to the plane of energy transport. While transverse waves are moving at a constant speed, their wavelengths increase, increasing their speed and distance. In a uniform medium, the length of a light wave changes with the amount of energy that it moves.

Light waves are not able to travel through a solid or liquid material, but they do move through a medium that is relatively uniform in density. This property allows them to pass through the medium. The speed of the pulses depends on the properties of the medium. A dense medium, such as a solid, causes the light to bend, while an airy one bends, causing the sound to travel through it.

## Anatomy of an Electromagnetic Wave

If you’re interested in learning about radio waves, you probably have some basic questions about electromagnetic waves. They’re created when electric and magnetic fields vibrate in waves. These waves travel at the speed of light, which makes their properties unique. The frequency of an electromagnetic wave is measured in Hertz (Hz). It’s also known as the amplitude of the signal. To understand the different types of electromagnetic waves, it’s helpful to understand how they work.

When an electrical current is accelerated, an electromagnetic wave occurs. This is a self-perpetuating process. The frequency of a wave is the number of times the wave crests pass a point within a second. The wavelength, in contrast, measures the distance between the peaks and the points on the wave’s surface. The shorter the wavelength of an electromagnetic field, the more energy is required to generate the waves.

Electromagnetic waves have similar characteristics to ocean waves. They occur at right angles to a constant companion wave in a magnetic field. When an electric current is accelerated, an electromagnetic wave travels at the speed of light. The wavelength is the distance between the crests. In the case of radio waves, the frequency is one per second. This means that an electric current in one wave is absorbed by a certain material. As the electrical current is accelerated, the resulting wave is an electromagnetic wave.

## Why Don’t Electromagnetic Waves Require a Medium?

There are many misconceptions about electromagnetic waves, but one of the most important is that they don’t require a medium to propagate. This is because the energy emitted by a moving electric charge creates a changing magnetic field at point X and a stationary magnetic field at point Y, and this process repeats itself repeatedly. In contrast, sound waves, water waves, and mechanical waves all require a medium for their energy to travel. By contrast, light and radiowaves do not. They are the only two types of waves that do not need a medium for propagation, so this is a big benefit.

Light doesn’t require a medium to travel. It’s experimentally constant, unlike sound. While sound travels through a medium, electromagnetic waves don’t. As they propagate, they generate a magnetic field and an electric field. The magnetic field pushes molecules in the air, which causes them to vibrate. When we observe light, we can see that it is an example of a phenomenon that doesn’t require a physical medium.

When light reaches the opposite of a magnetic field, the magnetic field pushes those molecules away from each other. While sound is always traveling through a medium, electromagnetic waves travel through space without it. In contrast to sound, which requires a medium, electromagnetic waves do not. Instead, they generate magnetic and electric fields as they propagate. These fields are constantly generating, and are therefore inexhaustible.

## Which Waves Can Travel Without a Medium?

Sound, light, and radio waves all require a medium to travel. While sound cannot travel through a vacuum, electromagnetic waves do not require a medium to propagate. In fact, these types of waves are capable of bridging great distances. This is why they’re often used to study how light and radio waves work. You can create a concept map on a white board to help students visualize the difference.

A medium is needed to transmit electromagnetic waves. Electromagnetic waves can travel through air, solid materials, and even a vacuum. Because they’re generated by charged particles, they can pass through empty space. The motion of a blue ball represents the motion of particles in a solid material. If it moves, these particles will move. That’s because electromagnetic waves don’t need a physical medium to travel.

Besides air and solid media, electromagnetic waves can travel through empty space. This makes them ideal for use in space. They can travel at high speeds without a medium, which makes them a great choice for use in remote locations. However, they must be carried through a material medium to be able to reach their destination. This is not always possible, as electromagnetic waves can be absorbed by the air, but they can be transmitted through it.
