Information: - Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies as high as 300GHz to as low as 3kHz, though some definitions describe waves above 1 or 3 GHz as microwaves, or include waves of any lower frequency.
