Similarly, oscillations of electrons in an antenna … WebSep 11, 2015 · Methods by which the correlated color temperature and the distribution temperature of a light source may be calculated from a knowledge of the spectral power distribution of the source are described.
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…
