Frequency and wavelength have an inverse relationship, meaning that as the frequency increases, the wavelength decreases, and vice versa.
To further illustrate this relationship, let’s take a look at the electromagnetic spectrum as a whole. At one end of the spectrum, we have high-frequency, high-energy waves such as gamma-rays and X-rays. These waves have short wavelengths, measuring in nanometers or even smaller. On the other end, we have low-frequency, low-energy waves like radio waves. These waves have long wavelengths, measuring in meters or even kilometers. Between these extremes, we find waves of varying frequencies and wavelengths, including microwaves and infrared waves.
| Wave Type | Frequency Range | Wavelength Range |
|---|---|---|
| Gamma-rays | 10^19 Hz – 10^24 Hz | < 10 picometers |
| X-rays | 10^16 Hz – 10^19 Hz | 10 picometers – 10 nanometers |
