Ultraviolet catastrophe - Wikipedia
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.

Ultraviolet Catastrophe | Quantum Mystery & Breakthrough
2024年5月27日 · The phenomenon known as the Ultraviolet Catastrophe stands as one of the pivotal mysteries in the history of physics, one that catalyzed a significant breakthrough in quantum mechanics. This term refers to a theoretical problem that arose from classical physics’ inability to correctly predict the energy distribution of blackbody radiation.
Because small wavelengths correspond to the ultraviolet end of the spectrum, this puzzle was known as the ultraviolet catastrophe. Figure 27.2 shows the issue, comparing the theoretical predictions to the actual spectrum for an object at a temperature of 5000 K.

2023年12月13日 · The ultraviolet catastrophe was a perplexing issue in physics during the late 1800s. Scientists, using classical physics, predicted that the intensity of radiation emitted by a black body would skyrocket to infinity as the frequency of the radiation increased, particularly in the ultraviolet range.
Blackbody Radiation and the Ultraviolet Catastrophe
Ultraviolet Catastrophe: Planks Breakthrough in Blackbody Radiation. Physicists derived mathematical expressions for the blackbody curves using well-accepted concepts from the theories of classical mechanics and classical electromagnetism.
