WebJan 2, 2024 · For any shorter wavelength, Wein's formula matches with the experimental result but not consistent for longer wavelength whereas formula given by Rayleigh-Jeans makes a good performance for longer wavelength but no longer works for the experimental data used for analyzing energy density for comparably shorter wavelength. The Rayleigh–Jeans law agrees with experimental results at large wavelengths (low frequencies) but strongly disagrees at short wavelengths (high frequencies). This inconsistency between observations and the predictions of classical physics is commonly known as the ultraviolet catastrophe. 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.
