radio waves

1. Waves at the end of the electromagnetic spectrum with the lowest frequency (less than 300 megahertz ) and the longest wavelength (from a few feet to many miles). Because of their low frequency, radio waves carry very little energy compared to other electromagnetic waves . ( See Planck's constant .)

Notes

Radio waves can pass through the atmosphere and therefore are very useful for communication. Commercial, short-wave, and citizens' band radio are broadcast with radio waves, as is television.
