In 1910, Peter Debye derived Planck's law of black-body radiation from a relatively simple assumption. He decomposed the electromagnetic field in a cavity into its Fourier modes, and assumed that the energy in any mode was an integer multiple of , where is the frequency of the electromagnetic mode. Planck's law of black-body radiation follows immediately as a geometric sum. However, Deby… WebOnce the photons are absorbed, the carriers come out from the original state and overcome an energy barrier but still stay in the material. Then it can be categorized as internal …
