WebThe Rayleigh scheme for counting modes. We need to evaluate the number of modes which can meet this condition, which amounts to counting all the possible combinations of the integer n values. An approximation can be made by treating the number of combinations as the volume of a three-dimensional grid of the values of n, an "n-space". WebFeb 13, 2016 · Wien's law is an approximation to Planck's law for low temperatures (or high frequencies); i.e., for . The key to showing this is to approximate in Planck's law for low temperatures (or high frequencies). The tilde in your statement of Wien's law is just indicating that the expression on the right side does not include an overall constant factor.
