Radio waves and then also it could be infrared or microwave cause they are longer than any other type of waves.
Radio is used in radio transmission - by taking large wavelengths and conducting them by using antennas to cover large distances.
Microwaves are used in all wireless communication and then also can be concentrated to be used for transferring heat.
Infrared is night vision and thermography. It can also be used for heating as well
which waves have wavelengths longer than those of visible light? Give an example of how each kind of wave is used.
