ultraviolet catastropheとは 意味・読み方・使い方

名詞

ultraviolet catastrophe

1. (physics) 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.

使用する際の注意点

• This does not literally refer to the explosion of ultraviolet radiation, rather any radiation shorter than a specific limiting size of propagating radiation in a set sized cavity, dependent on the size of the cavity.
