If λm denotes the wavelength at which the radiative emission

Home » Thermal Physics » Thermal Properties of Matter » Question

If λ_m denotes the wavelength at which the radiative emission from a black body at a temperature T K is maximum, then

1. λ_m ∝ T^-1
2. λ_m ∝ T⁴
3. λ_m is independent of T
4. λ_m ∝ T

Correct Option: A

From Wein’s displacement law
λ_mT = constant
⇒ λ_m ∝ T^–1
