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…

The result, Eq. (20), is the well-known Stefan-Boltzmann law. Similarly, Eq. (22) gives the integrated photon radiance. therapeutic chairs for adults
