Question

The power radiated by a black body is P and it radiates maximum energy at wavelength, $\lambda $₀ . If the temperature of the black body is now changed so that it radiates maximum energy at wavelength ${3 \over 4}{\lambda _0}$, the power radiated by it becomes nP. The value of n is

${3 \over 4}$

${4 \over 3}$

${{256} \over {81}}$

${{81} \over {256}}$
