Named after the German Physicist Wilhelm Wien, Wien’s law says that objects of different temperatures release spectra that peak at different wavelengths. Hotter objects appear blue because they emit radiations of shorter wavelengths. Likewise, cooler objects appear reddish because they emit radiation of longer wavelengths.
Therefore, in 1893, Wien’s law or Wien’s law of displacement was derived, which states that at wavelengths that are inversely proportional to temperatures, the black body radiation has different temperature peaks.
Mathematical representation of the law:
λmax = b/T
Where,
b denotes Wien’s displacement constant = 2.8977*103 m.K
T denotes the temperature in kelvins
