Electro-magnetic waves used in radio communications to carry information.
 

The frequencies of electromagnetic waves, generally between 10 kHz and 1 THz, corresponding to a wavelength of between 30 km and 0.3 mm. Such waves are used to operate cavity resonators in particle accelerators.

The frequency range from 10 kHz to 100 GHz used for transmitting data, audio, or video.
