3) Spheres A and B are made of the same material and have equal diameters. The,spectrum of thermal radiation from sphere A peaks at a waveiength one -quarter at which sphere B peaks. What can you say about the temperature of these two spheres? 4) For the two spheres in problem 3, what is the ratio of PA/PB, the power radiated by A to that radiated by B
