The power radiated by a black body is P, and it radiates maximum energy around the wavelength lambda_(0) . If the temperature of the black body is now changed so that it radiates maximum energy around a wavelength 3lambda_(0)//4 , the power radiated by it will increase by a factor of

Assertion : For higher temperature, the peak emission wavelength of a black body shifts to lower wavelengths. Reason : Peak emission wavelength of a black body is proportional to the fourth power of temperature.
