How does quantum physics explain black body radiation?
The issue about black body radiation that stumped physicists before the advent of quantum physics was that there was nothing limiting the energy levels of this radiation, which resulted in infinities in the equations. Once quantum physics was brought into play by Max Planck, there were certain energy levels that were allowed, and only those. The result was that the infinities in the equations, caused by a continuum of possible energy transfers, disappeared.
