The thermal emissivities of two bodies A...

The thermal emissivities of two bodies A and B are 0.02 and 0.09, respectively. `lamda_A` and `lamda_B` are the wavelengths corresponding to maximum intensity of radiations and `lamda_A` is shifted from `lamda_B` by ` mu m` . If the surface area and the total power radiated by the bodies are same, then calculate the temperature of B, given temperature of A is 5000 K.
