A black plane at temperature T₁ is parallel to a similar hotter plane at temperature T₂. In vacuum, what is the net energy flux between the two planes? If a third black plane is inserted between the first two and allowed to come to an equilibrium temperature Ta; find T₃ in terms of Ti and T₂. What is the new net energy flux between the original two planes? How would this change if n additional planes were added?
