Derive wien's displacement law from planck

WebWien’s displacement law states that the wavelength with the peak emissive power is inversely proportional to the temperature of the black body. This law gives the relation … Webtrophysics. Specifically, I will discuss the history of Wien’s Displacement Law, including how it was developed and original uses. I will then derive Wien’s Displacement Law from Planck’s Law. I will show how Wien’s Displacement Law can be used to derive the temperature of stars from stellar spectra observations.
