Question

The energy spectrum of a black body exihibits maximum around a wavelength λo. The temperature of the black body is now changed such that the energy is maximum around a wavelength $$3$$λ$$o/4$$. The power radiated by the black body will now increase by a factor of

Infinity Learn · Accepted Answer

According to Wien's displacement law, λ$$m1T1=$$λ$$m2T2$$∴ λ$$0T1=3$$λ$$0/4T2or$$       $$T1T2=34$$            ...(i)We$$ know that    $$E1E2=T14T24$$∴   $$E2E1=T2T14$$        ....$$(ii)From$$ eqns. $$(i) and (ii), We get            $$E2E1=434=25681$$

The energy spectrum of a black body exihibits maximum around a wavelength $λ_{o}$ . The temperature of the black body is now changed such that the energy is maximum around a wavelength $3 λ_{o} / 4$ . The power radiated by the black body will now increase by a factor of
