Please explain with every step how to solve this equation. I have seen it worked out before so I know the math and the answer but I really need it explained well so that I understand it. Find the frequency and wavelength of a 50 Mev Gamma ray photon
Question #1 a) Plot the energy spectral density p(2) of black-body radiation at T=3000 K and at 7= 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.)

Hello, This is a follow-up question for part b. For part "b", I supposed that the wavelength of maximum intensity for the following elements is: 1) Sun: 0.500µm 2) Light bulb: 0.966µm 3) Earth: 9.659µm Please note that these measurements are merely hypothetical and are not the actual wavelength radiations. These are just random numbers. Can you help me understand the formula for part "c" so that I can implement the answers from part "b" and figure out the temperatures of the sun, light bulb, and the Earth? Thank you, -Fredrick Beckmann
