the maximum emitted wavelength is inversely proportional to the its absolute temperature

Wilhelm Wien is German Physicist who received the Nobel Peace Prize for Physics for his law of displacement regarding radiation emitted by the black body.

In Wien's experiment it was found that when the temperature of the source increases, then the wavelength for which the radiant energy becomes maximum decreases. This displacement towards the lower wavelength side as temperature increases is termed as displacement law.

So if T, the temperature of the source in kelvin and lambda m is the wavelength for which the energy is maximum. Then lambdam *T = constant. This constant is known as Wien's constant, whose value is 5.67 x 10-8 mK.
