Questions
A black body radiates maximum energy at wavelength when its temperature is T. Now temperate of the black body is increased by 50%. Then the percentage change in wavelength at which the black body will radiate maximum energy is
detailed solution
Correct option is B
(2)By Wien's displacement Law,T'λ'=Tλ ⇒ λ'=TT' . λ=T1.5T × λ=2λ3.∴ Decrease in wavelength =λ−λ'λ × 100%=33.33%Talk to our academic expert!
