Electromagnetic waves have both magnetic as well as an electric field. They are classified based on their frequency. Following are the different types of electromagnetic waves:
- Radio waves: These are the longest wavelength electromagnetic waves which are used for transmitting data from radio, satellites, and radar.
- Microwaves: These waves are measured in centimetres and are used for transmitting information and for cooking food.
- Infrared: These waves are also known as near and far-infrared. The human body is an example of a body that gives off infrared waves.
- Visible light: The wavelength range of visible light is between 390 to 700 nm.
- UV waves: Ultraviolet waves are obtained from the Sun.
- X-rays: These waves are used for medical purposes to take pictures of bones.
- Gamma rays: These rays are the shortest waves in the electromagnetic spectrum.
