Infrared is an invisible spectrum of light that is all around us, but what color is it? Though it is invisible to the human eye, scientists and engineers have developed ways to see and measure infrared light, allowing us to answer the question of what color it is. In this article, we’ll explore the science of infrared light and discover its true color.
- How To Use Infrared:
1. Choose an infrared light.
2. Set up the infrared light to the desired area.
3. Connect the infrared light to a power source.
4. Adjust the settings on the light as needed.
5. Turn on the infrared light.
6. Monitor the area using infrared equipment.

What is Infrared Light?
Infrared light is a type of electromagnetic radiation that is invisible to the human eye. It has a range of frequencies and wavelengths that fall between visible light and microwaves on the electromagnetic spectrum. Infrared radiation is used for many everyday applications, including remote sensing, communication, and heat transfer.
Infrared light is divided into three different categories: near, mid, and far. Near infrared has the shortest wavelengths and is closest to visible light on the spectrum. Mid infrared has a longer wavelength than near infrared, and far infrared has the longest wavelength of all.
Infrared radiation is used in a variety of ways, such as transmitting television signals and providing heat energy. It can also be used to detect the presence of objects, such as in night vision systems.
What Color is Near Infrared?
Near infrared light has a wavelength that is just beyond the visible spectrum. It is invisible to the human eye, so it does not appear to have any color. However, some animals, such as snakes, can see near infrared light.
Near infrared light is often used in photography, as it can be used to capture images that are not visible to the human eye. For example, near infrared light can be used to capture images in low light conditions, such as at night or in fog.
What Color is Mid Infrared?
Mid infrared light has a longer wavelength than near infrared light, and it is also invisible to the human eye. Mid infrared light is often used in night vision systems, as it can be used to detect the presence of objects that are not visible to the human eye.
Mid infrared light can also be used in medical imaging, such as thermography. This type of imaging uses mid infrared light to detect subtle changes in temperature on the surface of the body, which can indicate the presence of certain diseases or medical conditions.
What Color is Far Infrared?
Far infrared light has the longest wavelength of all infrared light, and it is also invisible to the human eye. Far infrared light is often used for heat transfer, as it is capable of penetrating deep into the body.
Far infrared light is also used in medical imaging, as it can be used to detect changes in temperature that are not visible to the human eye. Far infrared light can also be used to detect the presence of objects that are not visible to the human eye, such as in night vision systems.
Few Frequently Asked Questions
What Color is Infrared?
Answer: Infrared is not actually a color, but it is a type of invisible light that has a longer wavelength than visible light. It is located just beyond the visible spectrum of light and is not visible to the human eye. When infrared light is referred to as a color, it is often described as a deep red. The term “infrared” is derived from the Latin words “infra” meaning “below” and “red” meaning “color”.
What Wavelength Does Infrared Light Have?
Answer: Infrared light has a wavelength that is longer than visible light. It is located on the electromagnetic spectrum between 700 nm and 1 mm. This range of wavelength is often referred to as the infrared region and includes three main categories: near infrared, mid infrared, and far infrared.
What Are the Uses of Infrared Light?
Answer: Infrared light is used in a variety of fields, including medicine, astronomy, and engineering. In medicine, infrared light is used in diagnostics, to detect disease, and to treat conditions such as arthritis. In astronomy, infrared light is used to study distant objects in the universe, such as stars and galaxies. In engineering, infrared light is used in remote control devices, such as television remotes, and in thermal imaging.
What Effects Does Infrared Light Have on the Human Body?
Answer: Infrared light has a variety of beneficial effects on the human body. It helps to improve circulation, reduce inflammation, and promote healing. It can also help to reduce pain, improve skin tone, and reduce the appearance of wrinkles. Additionally, infrared light can help to improve sleep quality and reduce stress levels.
Is Infrared Light Dangerous?
Answer: Infrared light is generally safe for human use, and it does not pose any dangers to health. However, it is important to use infrared light in moderation and to avoid overexposure. Prolonged exposure to infrared light can cause eye damage and skin irritation. Therefore, it is important to wear protective goggles and clothing when using infrared light.
What Are Some Examples of Infrared Light?
Answer: Some examples of infrared light include sunlight, heat lamps, and infrared lasers. Sunlight is the most common source of infrared light and is composed of both visible and invisible light. Heat lamps emit infrared light that is used to warm up certain objects. Infrared lasers are used in laser therapies and laser treatments, and they can be used to treat a variety of conditions.
