In physics, Wien's displacement law states that the black-body radiation curve for different temperatures will peak at different wavelengths that are inversely proportional to the temperature.
May 22, 2019 · Wien’s Displacement Law. As can be seen from the figure, the blackbody radiation curve for different temperatures peaks at a wavelength inversely proportional to the temperature. Wien’s law (named after a German physicist) describes the shift of that peak in terms of temperature.

What is Wien's law?
Wien’s law or Wien’s displacement law, named after Wilhelm Wien, was derived in the year 1893 which states that black body radiation has different peaks of temperature at wavelengths that are inversely proportional to temperatures.
b is a constant of proportionality, called Wien's displacement constant and equals 2.897 768 5(51) × 10 –3 m K (2002 CODATA recommended value) The two digits between the parentheses denotes the uncertainty (the standard deviation at 68.27% confidence level) in the two least significant digits of the mantissa.
Wien’s Displacement Law Formula. Wien’s Displacement law is expressed mathematically as follows: \( \lambda_{\max }T=b \) Where, \( \lambda_{\max } \) = wavelength at which the blackbody dominantly radiates. b = Wien’s constant (\( 2.897 \times 10^{-3} \mathrm{mK} \)) and. T = temperature in kelvin. Wien’s Constant
