Here's a breakdown:
* Electromagnetic waves are disturbances that travel through space at the speed of light. They are made up of oscillating electric and magnetic fields.
* Frequency is a measure of how often these oscillations occur.
* Higher frequency means more oscillations per second, and the wave carries more energy.
* Lower frequency means fewer oscillations per second, and the wave carries less energy.
Examples:
* Radio waves have frequencies in the range of kilohertz (kHz) to gigahertz (GHz).
* Microwaves have frequencies in the range of gigahertz (GHz).
* Visible light has frequencies in the range of hundreds of terahertz (THz).
* X-rays have frequencies in the range of petaHertz (PHz) to exahertz (EHz).
Relationship to wavelength:
The frequency of an electromagnetic wave is inversely proportional to its wavelength. This means that a wave with a higher frequency will have a shorter wavelength, and a wave with a lower frequency will have a longer wavelength. The relationship between frequency (f) and wavelength (λ) is given by:
```
c = fλ
```
where c is the speed of light.
