A pure blackbody emission in Rayleigh–Jeans regime predicts α ∼ +1. 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.
WebNov 22, 2024 · The Rayleigh-Jeans theory was constructed on the notion that when the walls of an object are in thermal equilibrium, in other words, the temperature of the walls is equal to the "temperature" of radiation. We will see what we mean by the "temperature" of an electromagnetic wave. If we take the walls of a cavity to consist of oscillating charged ... WebRayleigh-jeans law: A black body in thermal equilibrium will emit radiation in all frequency ranges, and as the frequency increases, so does the energy of the radiation emission. The …
