Precautions while using Microwaves
Electromagnetic radiation spectrum
Microwaves, like visible light, are a part of the electromagnetic radiation spectrum. They are extremely high frequency radio waves. As the frequency of radiation increases, its wavelength decreases, so very high frequencies correspond to very short wavelengths; hence the name microwaves. Infrared radiation, ultraviolet light and X rays are also electromagnetic radiations, but have even shorter wavelengths than microwaves.
