Setting this derivative equal to zero to determine the maximum gives the equation It is based on the fact that hotter objects have more energy than cooler objects and therefore emit more radiation at higher frequencies than at lower frequencies. Wien displacement law formula the wien's displacement law provides the wavelength where the spectral radiance has maximum value. Wien's approximation (also sometimes called wien's law or the wien distribution law) is a law of physics used to describe the spectrum of thermal radiation (frequently called the blackbody function).

B is the wien's displacement constant = 2.8977*103 m.k; This law is in agreement with the experimental blackbody radiation curve (figure \(\pageindex{2}\)). Wien's law planck's equation for the exitance per unit wavelength interval (equation 2.6.1) is m c = 1 λ5(ek / λt − 1), in which i have omitted some subscripts. Wien's displacement law differentiating planck's function and setting the derivative equal to zero yields the wavelength of peak emission for a blackbody at temperature t λm ≈ 2900 t where λm is expressed in microns and t in degrees kelvin.
