One of the first radar devices developed during world war ll used microwave radiation of a wavelength that triggers the rotation of water molecules. this was an unfortunate coincidence because it Absorption of microwave radiation by water in the atmosphere interferes with the detection of intended objects.
Microwave frequencies range from 1,000 to 300,000 MHz (or 30 cm to 1 mm wavelength).
The microwave frequency is approximately 2.45 GHz
According to the Encyclopedia Britannica, microwaves have frequencies ranging from about 1 billion cycles per second, or 1 gigahertz (GHz), up to about 300 gigahertz, and wavelengths ranging from about 30 centimeter's (12 inches) to 1 millimeter (0.04 inch).
