An electromagnetic wave with a frequency in the range of 100 megahertz to 30 gigahertz (lower than infrared but higher than other radio waves). Microwaves are used in radar, radio transmission, cooking, and other applications. Microwaves are generated naturally by many astronomical phenomena and are found in cosmic background radiation.
