Derivation of Wien's+Reyleigh-Jean's Laws from Planck's Law

[QUOTE="TSny, post: 5376454, member: 229090"] Welcome to PF! In going from your next to last equation to your last equation, you did not solve for ##e^{hv/kT} ## correctly. But you don't need to go through all of this. Wien's law is an approximation to Planck's law for low temperatures (or high frequencies); i.e., for ##kT << h \nu##. The key to showing this is to approximate ##\frac{1}{e^{hv/kT}-1}## 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. It just shows the functional dependence on various parameters. [/QUOTE]
