radio wave
A very low frequency electromagnetic wave (from roughly 30 kilohertz to 100 gigahertz). Radio waves are used for the transmission of radio and television signals; the microwaves used in radar and microwave ovens are also radio waves. Many celestial objects, such as pulsars, emit radio waves. See more at electromagnetic spectrum.

radio wave - Travels like rays of light, so it takes its name from Latin radius, "spoke of a wheel; ray of light."
