Planck's law describes the unique and characteristic spectral distribution for electromagnetic radiation in thermodynamic equilibrium, when there is no net flow of matter or energy. Its physics is most easily understood by considering the radiation in a cavity with rigid opaque walls. Motion of the walls can affect the radiation. If the walls are not opaque, then the thermodynamic equilibrium is not isolated. It is of interest to explain how the thermodynamic equilibrium is attain… Web26 de mar. de 2016 · What Planck was saying was that the energy of the radiating oscillators in the black body couldn’t take on just any level of energy, as classical physics allows; it could take on only specific, quantized energies. In fact, Planck hypothesized that that was true for any oscillator — that its energy was an integer multiple of
