Question

The spectral distribution of radiation from a black body at T1=3000 KT_1 = 3000\text{ K} has a maximum at wavelength λmax\lambda_{\text{max}}. The body cools down to a temperature T2T_2. If the wavelength corresponding to the maximum of the spectral distribution at T2T_2 is 1.21.2 times of the original wavelength λmax\lambda_{\text{max}}, then the temperature T2T_2 is ________ K (round off to the nearest integer).
