Blackbody Radiation Question 5: Comparing Planck's Law for Different Stars

Assuming that the spectrum of blackbody radiation is given by Planck's law (2.1), prove the following. (a) Show that the total energy density of blackbody at temperature T is given by U=aB T^4 where aB=(8 πκB^4)/(c^3 h^3) ∫0^∞ (x^3 d x)/(e^x-1) (Note: this integral can be evaluated exactly and can be shown to be equal to .π^4 / 15 .) (b) Show that the total energy radiated in unit time from unit area on the surface of a blackbody is given by σT^4, where σ=(c aB)/(4) (c) Show that the frequency v
