The medium may absorb, emit and scatter radiation and the boundaries of the slab are diffuse emitters and reflecters kept at the same uniform temperature. The medium is gray and because the wall temperatures are equal, symmetry can be exploited. ENDDIS ************************************************************ Group 1.
