Wilhelm Wien formulates Wien's displacement law

In 1893, Wilhelm Wien derived Wien's displacement law using a thermodynamic argument, establishing the inverse relationship between peak wavelength and temperature.

Wien deduced the law theoretically in 1893, following Boltzmann's thermodynamic reasoning. The law states that the black-body radiation curve peaks at wavelengths inversely proportional to temperature. This derivation described the shift of the spectrum toward shorter wavelengths as temperature increases, predating Planck's more general equation.
