Ultraviolet Radiation
UV radiation is part of the light spectrum that ranges from the earth to the sun. UV rays have shorter wavelengths than visible light making then invisible to the human eye. However, some insects are able to see UV rays. It is called Ultraviolet light because its electromagnetic waves have frequencies higher than what is seen by humans, which is the color violet. UV light can be found in sunlight and is released by electric arcs, which are electric breakdowns.

Famous quotes containing the words ultraviolet and/or radiation:
“As if the musicians did not so much play the little phrase as execute the rites required by it to appear, and they proceeded to the necessary incantations to obtain and prolong for a few instants the miracle of its evocation, Swann, who could no more see the phrase than if it belonged to an ultraviolet world ... Swann felt it as a presence, as a protective goddess and a confidante to his love, who to arrive to him ... had clothed the disguise of this sonorous appearance.”
—Marcel Proust (1871–1922)
“There are no accidents, only nature throwing her weight around. Even the bomb merely releases energy that nature has put there. Nuclear war would be just a spark in the grandeur of space. Nor can radiation “alter” nature: she will absorb it all. After the bomb, nature will pick up the cards we have spilled, shuffle them, and begin her game again.”
—Camille Paglia (b. 1947)
