WebMar 7, 2011 · Fullscreen. 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. WebFigure 1.1.2 : Blackbody radiator is any object that is a perfect emitter and a perfect absorber of radiation.
