4. The sun approximates an ideal blackbody radiator at a temperature of 5825K.
(a) By Wien’s Law, what is the peak wavelength of this distribution?
(b) What is the energy of a blackbody photon at this wavelength?
(c) Is this photon in the visible band of the electromagnetic spectrum and why or why not?
(d) The Cosmic Microwave Background has a nearly perfect blackbody spectrum with a temperature of 2.73K. What is the peak blackbody wavelength?
