The ultraviolet catastrophe, also called the Rayleigh–Jeans catastrophe, was the prediction of late 19th century to early 20th century classical physics that an ideal black body at thermal equilibrium would emit an unbounded quantity of energy as wavelength decreased into the ultraviolet range.
May 22, 2019 · The ultraviolet catastrophe is the error at short wavelengths in the Rayleigh–Jeans law (depicted as “classical theory” in the graph) for the energy emitted by an ideal black-body.
Nov 24, 2022 · The ultraviolet (UV) catastrophe, also called the Rayleigh–Jeans catastrophe, is the prediction of classical electromagnetism that the intensity of the radiation emitted by an ideal black body at thermal equilibrium goes to infinity as wavelength decreases (see figure \(\PageIndex{1}\) )\(^1\).
The ultraviolet catastrophe, also called the Rayleigh-Jeans catastrophe, was the prediction based on classical physics that an ideal black body at thermal equilibrium will emit more energy as the frequency of radiation increases than it was observed in experiments.
The ultraviolet catastrophe is the name given to a conflict between theory and the observation in classical physics. An ideal blackbody at thermal equilibrium emits radiation in all frequency ranges. It emits more energy as the frequency increases.
Sep 8, 2021 · Although the Rayleigh-Jeans law works for higher wavelengths \(\lambda\), it diverges as \(\lambda\) become low in value; this divergence for high frequencies is called the ultraviolet catastrophe.
Definition. The Ultraviolet Catastrophe describes the failure of classical physics to account for the observed spectrum of blackbody radiation at short wavelengths. Classical theory predicted infinite energy emission in the ultraviolet region, which contradicted experimental results.
