Questions
If denotes the wavelength at which the radiative emission from a black body at a temperature T K is maximum, then
a
λm∝ T4
b
λm is independent of T
c
λm ∝ T
d
λm ∝ T-1
detailed solution
Correct option is D
According to Wien's displacement law, the wavelength (λm) of maximum intensity of emission of black body radiation is inversel proporitonal to absolute temperature (T) of the black body. Therefore, Wien's law is λmT = constant or λm = constantT or λm∝1T or λm ∝ T-1Talk to our academic expert!
