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 usa… Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is ultraviolet catastrophe, spelled U-L-T-R-A-V-I-O-L-E-T- -C-A-T-A-S-T-R-O-P-H-E, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.

Definition

  1. 1
    A fault in classical physics, from the Rayleigh's law/Rayleigh-Jeans law outcomes at short wavelengths/high frequencies, that causes infinite amplification of shorter wavelength/higher frequency radiation inside a cavity, due to the application of equipartition theorem on black body radiation within a cavity.

Etymology

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.
