The power radiated by a black body is P and it radiates maximum energy at wavelength, $\displaystyle \lambda_0$. If the temperature of the black body is now changed so that it radiates maximum energy at wavelength $\displaystyle \frac{3}{4} \lambda_0$, the power radiated by it becomes nP. The value of n is
