Ultraviolet acti nonherapy syndrome has a set up of wavelengths of some 10 NM to 400 NM. Ultraviolet light is in the main divide into the near (4000- 3000A), the far (3000- 2000A), and the vacuum (2000- 40 A) ultraviolet component.

Most of the waves are blocked by the Ozone layer, in the earths upper atmosphere. The Ozone layer in the earths upper atmosphere, as hearty as atmospheric group O and nitrogen keeps rate to the fore all ultraviolet radiation with wavelengths shorter than 2900 A from scope the earths surface.

Ultraviolet rays! are sometimes known as Black Light, because near of them can not be seen at a time by human eyes.         Major sources of ultraviolet rays are: sun, lightning, or any other electrical sparks in the air.          Ultraviolet rays shorter than 320 NM can be used to kill bacteria and viruses.
