WebFeb 26, 2015 · This theorem was formulated in the middle of the 19th century, and we can demonstrate it now with the tools of statistical physics. It was natural for Rayleigh and Jeans to use it to try to describe the blackbody spectrum. Note that a harmonic oscillator has two quadratic degrees of freedom. Hence the average energy of a cavity mode is kT. WebMar 7, 2011 · Blackbody radiation is the maximum amount of energy an object can emit. This Demonstration shows how Max Planck was able to close the gap between the explanation of classical physics and the observed experimental data. His formula was derived by assuming that oscillating molecules emit energy as quantized discrete values.
