Question

State Wien's displacement law.

Answer 1

Hi

Wien's displacement law states that the black body radiations curve for different temperature peaks at a wavelength that is inversely proportional to the temperature .

Answer 2

Answer:

Wien's displacement law tells about the relationship of the absolute temperature of a blackbody and the wavelength of the thermal radiation at which the blackbody emits thermal radiation with maximum emissive power.

This law states that if the maximum emissive power of the thermal radiation of the blackbody is corresponding to the wavelength $\rm \lambda_{max}$, then it is related with the absolute temperature $\rm T$ of the body as

$\rm \lambda_{max} \cdot T = constant.$
