Question:

According to Wien's law, which of the following relationships holds true?

λmT=constant

λmT=constant

λm√T=constant

λm√T=constant

Solution:

Wien's displacement law states that the black body radiation curve for different temperatures peak at a wavelength inversely proportional to temperature. When the temperature of a blackbody radiator increases, the overall radiated energy increases and the peak of the radiation curve moves to shorter wavelengths. The relation is presented as λmT=constant
