How does the cool body know when to stop sending photons to the hot body? At equilbrium are each of them still continually sending photons to each other? Is each photon from the cool body at a lesser energy level than each one from the hot body? I don;t understand exactly how the 2 bodies end up...
Assuming no conduction and no convection will a colder body be able to send photons to a hotter body while the hotter body is sending photons to t. We all know that an equilibrium will result with a temperature somewhere between the two bodies but do the photons emitted by the cooler body...
