The Rayleigh-Jeans Radiation Law and its Derivation.

. . .

Derivation of Rayleigh-Jeans Law. . . . .

Between two end points there can be two standing waves, one for each polarization. In the following, the matter of polarization will be ignored until the end of the analysis and there the number of waves will be doubled to take into account the matter of polarization..

In terms of the relationship for the cube,. . Hence,.

. . . If. . Then,. . Hence,. . Thus,. .

. Hence,. . . .

. . The previous only considered one direction of polarization for the radiation. If the two directions of polarization are taken into account a factor of 2 must be included in the above formula..
