a) Plot the energy spectral density p(2) of black-body radiation at 7= 3000 K and at T = 5000 K. (These correspond to the apparent temperatures of "warm white" and "cool white" light bulbs.) (Note: Show both curves on a single graph, using a standard plotting software. Report the wave- length in nanometers.) b) For each of these two temperatures, at which wavelength is the radiation intensity maximum? (Note: Report the wavelengths in nanometers. Your answers should be consistent with the curves from part a), of course.)
