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.
Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light.On Earth, sunlight is filtered through Earth's atmosphere, and is obvious as daylight when the Sun is above the horizon.When the direct solar radiation is not blocked by clouds, it is experienced as sunshine, a combination of bright light and radiant heat. Ultraviolet C or (UVC) range, which spans a range of 100 to 280 nm. 2  The term ultraviolet refers to the fact that the radiation is at higher frequency than violet light (and, hence, also invisible to the human eye).
