In reference to Wien's displacement law, what is meant by displacement?
Change in position
Change in velocity
Change in the peak wavelength with the change in temperature
Change in acceleration
Answer
Displacement in Wien's displacement law refers to the change in the peak wavelength with the change in temperature. This law states that the peak wavelength of blackbody radiation is inversely proportional to the temperature of the blackbody. This means that as the temperature of a blackbody increases, the peak wavelength of its radiation decreases.
