Ultraviolet light, also known as UV light, is a  type of electromagnetic radiation that has a wavelength somewhere close to light and X-ray. It is used broadly all over the world, in everything from the generation of usable electric power to the many other regular uses for a simple black light. UV lights are used in various applications ranging from industrial, commercial and healthcare sectors.

The fundamental rule that makes UV light valuable is its destructive nature. Organisms behave and react differently when exposed to UV light. In addition to that basic destructive rule, inert materials and living organism show up distinctively in UV light than they do under the normal room, or white, light. Likewise, its effect on a single surface, for example, an ID card, a repair to old fashioned porcelain or a cracked apartment wall will also be uncovered under the dark light. US currency, traveler's check, and other delicate archive are likewise now mainly made to be certified by viewing under UV light.
