Rayleigh-Jeans Law & The Ultraviolet Catastrophe
WebAug 4, 2024 · The Rayleigh-Jeans law is the low frequency limit of the full curve, where the spectral radiance is inversely proportional to the wavelength to the fourth power. I am not entirely sure that this is the "tail" that you are referencing to, but I've personally encountered the term Rayleigh-Jeans tail in the context of the low frequency end of the radiation curve … In 1900, the British physicist Lord Rayleigh derived the λ dependence of the Rayleigh–Jeans law based on classical physical arguments, relying upon the equipartition theorem. This law predicted an energy output that diverges towards infinity as wavelength approaches zero (as frequency tends to … See more In physics, the Rayleigh–Jeans law is an approximation to the spectral radiance of electromagnetic radiation as a function of wavelength from a black body at a given temperature through classical arguments. For wavelength λ, it is: See more • Stefan–Boltzmann law • Wien's displacement law • Sakuma–Hattori equation See more • Derivation of Rayleigh-Jeans law • Derivation of modes a wave in a cube See more WebJan 19, 2024 · I'm reading about why the Rayleigh-Jeans formula failed to explain blackbody radiation curves. The Rayleigh-Jeans formula: $$ E = kT\left(\frac{8\pi\nu^2}{c^3}\right) $$ I see explanations saying that the part of the equation in parentheses related to the "number of standing waves that are able to fit into a blackbody cavity". fishing canyon creek lake
