In theory, all of the energy emitted by the walls of the blackbody radiator is eventually reabsorbed by the walls; that is, none escapes from the enclosure. Thus, a blackbody will, for the same area, radiate more total power and more power at a given wavelength than any other light source operating at the same temperature. Figure 1-3.
