For 10 points, identify this law that gives the energy distribution of radiation from a perfect blackbody and was named for a German physicist whose namesake constant figures prominently in it.
Integrating this expression over all frequencies and solid angles gives an expression for power as proportional to the temperature raised to the fourth, a result known as the Stefan-Boltzmann equation. This equation can be derived by assuming the quantization of photon energy and it reproduces both the Rayleigh-Jeans low-frequency limit and the Wien high frequency limit.
