1. Electromagnetic radiation in an evacuated vessel of volume Vat equilibrium with the walls at temperature T (black body radiation) behaves like a gas of photons having internal energy U = aVT4 and pressure P= (1=3)aT4, where a is Stefan's constant. %3D (a) Plot the closed curve in the P¡V plane for a Carnot cycle using black body radiation. (b) Derive explicitly the efficiency of Carnot engine which uses black body radiation as its working substance.
