词源

Coined by Paul Ehrenfest in 1911 in German. Ultraviolet represents that end of the spectrum, given that the visible spectrum represents a stand-in for the whole electromagnetic spectrum, and infrared and ultraviolet are stand-ins for the endpoints. This usage is similar to that represented by the logic behind the terms "redshift" and "blueshift", which assume endpoints of red and blue.
