The maximum energy is the thermal radiation from a hot source occurs at a wavelength of 11 xx 10^(-5) cm . According to Wien’s law, the temperature of this source (on Kelvin scale) will be n times the temperature of another source (on Kelvin scale) for which the wavelength at maximum energy is 5.5 xx 10^(-5) cm. The value of n is:
