WebPlanck’s blackbody radiation law is described, for instance, in the textbo oks of F eynman et al. [1963], Semat and Albright [1972], Liou [2002], and Rybicki and Lightman [2004]. WebThis assumption allowed Planck to derive a formula for the entire spectrum of the radiation emitted by a black body. Planck was unable to justify this assumption based on classical physics; he considered quantization as being purely a mathematical trick, rather than (as is now known) a fundamental change in the understanding of the world.
