Glossary term: Radio Waves
Description: Radio waves are the longest wavelength, lowest frequency, and lowest energy part of the electromagnetic spectrum. They range from a shortest wavelength of about 1 millimeter and frequency of 300 gigahertz, to many kilometers in wavelength and megahertz of frequency. Our atmosphere is transparent for most of this waveband, allowing radio telescopes to be located on the ground.Related Terms:
