Derive wien's displacement law from planck
WebIn 1900, Max Planck worked out the relationship between the radiation emitted by a blackbody as a function of temperature and wavelength, and in doing so sta... WebDec 5, 2011 · As a refresher exercise in modern physics, I want to derive Wien's displacement law: from Planck's formula: by differentiating R () and setting dR/d = 0. I get to an expression like this: If it wasn't for the "5kT " term by itself on the left-hand side of the equation, the solution would simply be: () (T) = hc / 5k which is Wien's law.

WebWien's displacement law is much weaker: it does not give a specific result for ρ ν but only constrains the form it may take in terms of some unknown function f. Finding f means deriving either Wien's distribution law or the full Planck law, both of which are stronger than the question at hand. – Emilio Pisanty Feb 19, 2013 at 0:43 1
