The outer surface areas of the two bodies are same. The two bodies emit total radiant power at the same rate. The wavelength λB corresponding to maximum spectral radiancy from B is shifted from the wavelength corresponding to maximum spectral radiancy in the radiation from A by 1.0 μm. If the temperature of A is 5802 K, calculate (a) the temperature
