Microwaves are a form of electromagnetic radiation with wavelengths ranging from one meter to one millimeter; with frequencies between 300 MHz (100 cm) and 300 GHz (0.1 cm).t indicates that microwaves are small, compared to waves used in typical radio broadcasting, in that they have shorter wavelengths. The boundaries between far infrared, terahertz radiation, microwaves, and ultra-high-frequency radio waves are fairly arbitrary and are used variously between different fields of study.
The shorter the wavelength, the more energetic the radiation, and the greater the potential for harm. Ultraviolet (UV) radiation that reaches the Earths surface is in wavelengths between 290 and 400 nm (nanometers, or billionths of a meter).This is shorter than wavelengths of visible light, which are 400 to 700 nm.UV-B includes light with wavelengths down to 280 nm, but little to no radiation below 290 nm reaches the Earthâs surface). UV-B causes damage at the molecular level to the fundamental building block of life deoxyribonucleic acid (DNA).
