Derive wien's displacement law from planck
WebWien's displacement law gives the frequency (or wavelength) at which the Planck law has the maximum specific intensity. Take the derivative with respect to frequency to find the … 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.
