Microwaves are electromagnetic waves with wavelengths ranging from as long as one meter to as short as one millimetre. Or equivalently with frequencies between 300 MHz (0.3 GHz) and 300 GHz (0.3–300 GHz). Microwaves lie in the electromagnetic radiation spectrum, between radio waves (Rf) and infrared (IR) frequencies, with relatively large wavelengths a form of energy, not heat.
This nonionizing radiation, incapable of breaking chemical bonds, is a form of energy that manifests itself as heat through interaction with the polar medium.
Microwaves use in many applications, also clothing. Some of the more well-known technologies such as the radar use microwave radiation to detect the range, speed, and other characteristics of remote objects (remote sensing). Furthermore, Microwave heating common in industrial processes for drying and curing products. And applications such as spectroscopy combined with electrochemistry; microwave enhanced electrochemistry.
