radio

Electromagnetic energy with a waveform having a frequency above the upper limit of the audio

range of 3 kHz and equal or less than the lower limit of the infrared light range of 300 GHz.At the low end of the range is extremely low frequency (ELF) radio, which operates at 30–300 Hz, and at the upper end of the range is extremely high frequency (EHF) radio, which operates at 30–300 GHz. See also electromagnetic spectrum, frequency, and Hz.
