प्रश्न
State the Wien's displacement law
उत्तर १
According to Wein's displacement law, as the temperature of a black body rises, the peak of the distribution curve shifts towards the shorter wavelength (λ).
Thus, λmT = b, a (constant)
where b = 2.898 × 10−3mK.
उत्तर २
It is observed that the wavelength, for which emissive power of a blackbody is maximum, is inversely proportional to the absolute temperature of the blackbody. This is Wien’s displacement law.
