Photoemission by Black Body Radiation A black body emits peak spectral intensity at 9000 On increasing its temperature total radiation power increases by 81 times At the initial temperature when peak radiation of black body is allowed to fall on a metal surface assume other radiation are blocked by a filter it does not cause any photoemission but after increasing temperature the peak radiation of black body causes electrons come out which are stopped by a potential equal to the excitation energy of H atoms for n 2 to n 3 Bohr level Find work function of metal
