Ultraviolet light is a form of radiation which is not visible to the human eye. It's in an invisible part of the electromagnetic spectrum. Radiated energy, or radiation, is given off by many objects: a light bulb, a crackling fire, and stars are some examples of objects which emit radiation. The type of radiation being emitted depends on the temperature of the object.
Ultraviolet. Ultraviolet light is in the range of the EM spectrum between visible light and X-rays. It has frequencies of about 8 Ã 10 14 to 3 Ã 10 16 Hz and wavelengths of about 380 nm (.000015 inches) to about 10 nm (0.0000004 inches). UV light is a component of sunlight; however, it is invisible to the human eye.aves and fields. EM radiation is created when an atomic particle, such as an electron, is accelerated by an electric field, causing it to move. The movement produces oscillating electric and magnetic fields, which travel at right angles to each other in a bundle of light energy called a photon.
