Rayleigh-jeans
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. For wavelength λ, it is: See more • Stefan–Boltzmann law • Wien's displacement law • Sakuma–Hattori equation See more 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.

At the time, there were two distinct models for blackbody radiation: the Rayleigh-Jeans law, which fit the measurements well at low frequencies, and Wien’s law, which worked well at high frequencies, but neither worked everywhere.
