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:
“Like ultraviolet rays memory shows to each man in the book of life a script that invisibly and prophetically glosses the text.”
—Walter Benjamin (1892–1940)
“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)
