WebJul 28, 2024 · Black body is not capable of these complicated processes because that is the desideratum in the definition - to get a simple model. Then, there is the independence of the composition of the body. This is also effectively part of the definition, because the idea was to have a concept of body whose emission does not depend on these details. WebPlanck Radiation Formula From the assumption that the electromagnetic modes in a cavity were quantized in energy with the quantum energy equal to Planck's constant times the frequency, Planck derived a radiation formula.
