An electromagnetic wave within the range of radio frequencies.
(Telecommunications) an electromagnetic wave of radio frequency
an electromagnetic wave having a wavelength between 1 millimeter and 30,000 meters, or a frequency between 10 kilohertz and 300,000 megahertz.
An electromagnetic wave having a low frequency and long wavelength. Radio waves are used for the transmission of both radio and television broadcasts. They also include the microwaves used for cooking. Some celestial objects, such as pulsars, also 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."
