Lummer and Kurlbaum modeled these objects as a cavity with a miniscule hole.
Lummer and Kurlbaum modeled these objects as a cavity with a miniscule hole. A law derived by multiplying the Bose-Einstein distribution by the density of states gives these objects' peak energy as roughly 2.8 times the Boltzmann constant times temperature, in accord with Wien's law. A function of the frequency of these objects squared fails at low wavelengths in the ultraviolet catastrophe. That law, the Rayleigh-Jeans law, was improved by Planck. Their emissive power is proportional to temperature to the fourth power. For 10 points, name these theoretical bodies named for their ability to absorb and re-radiate all incident electromagnetic radiation.
