Most energetic form of radio waves.
Radio waves having wavelengths of less than 20 centimeters.
That portion of the electromagnetic spectrum lying between uhf (ultrahigh frequency) radio waves and heat (infrared) waves. Microwaves are used to generate heat, especially in some types of diathermy. They may cause heat damage to tissues. ... (12 Dec 1998) ... 
Type: Term Pronunciation: mī′krō-wāvz Definitions: 1. That portion of the radio wave spectrum of shortest wavelength, including the region with wavelengths of 1 mm-30 cm (1000-300,000 megacycles per second). Synonyms: microelectric waves
Electromagnetic waves longer than infra-red but shorter than radio, in the region of the spectrum between about 3x108Hz and 3x1011Hz and wavelengths between about 10-4m and 1m. See also: Wavelength.
Electromagnetic waves whose frequencies lie between the far infrared and some lower frequency limit. Although not clearly bounded, the microwave region is commonly regarded as lying between 300 MHz and 300 GHz.
Waves of electromagnetic radiation that oscillate from approximately 109 to 3 x 1011Hz. (cycles per second). SLAC's klystrons produce microwaves of 2,856 MHz.
Commonly, very short radio waves having wave lengths of 1 millimeter to 30 centimeters. While the li
