Wavelength

Radio waves have the longest wavelength in the Electromagnetic spectrum. Radio waves are EM waves that have the wavelength between 1 millimeter to 100 kilometers. They range out from the length of a football to larger than our planet.

Radio Waves Frequency

Frequency

Radio waves have frequencies from 300 GHz to as low as 3 kHz.

Energy

Radio waves are used to transmit radio and television signals.

FM radio waves are shorter than AM radio waves. For example, an FM radio station at 100 on the radio dial (100 megahertz) would have a wavelength of about three meters. An AM station at 750 on the dial (750 kilohertz) uses a wavelength of about 400 meters.
