Mechanical Properties Of Fluids

Question

Wired Faculty App

State Wien’s displacement law.

Solution

Wien’s displacement law states that the product of wavelength of maximum emission and the absolute temperature of the body is constant.

straight lambda subscript straight m straight T equals constant equals 0.2892 space cm space straight K

According to this law, the wavelength of maximum emission decreases with the increase in temperature of the body.
