Rayleigh jeans regime
WebIn physics, the Rayleigh-Jeans Law, first proposed in the early 20th century, attempts to describe the spectral radiance of electromagnetic radiation at all wavelengths from a black body at a given temperature. For wavelength λ, it is; where c is the speed of light, k is Boltzmann's constant and T is the temperature in kelvins..

Relativistic effects (equal-arrival-time surface effect) would soften it to α ∼ +0.4 (e.g., Beloborodov 2010; Deng & Zhang 2014), which is still too hard compared to the data.
