A pane of glass having transmissivity of 0.8 between wavelengths of 0 to 4 ?m and 0 above 4 ?m is subjected to direct radiation from the sun on one side and from a room on the other side. Assume that the sun is a black body at 6000 K and the room is a black body at 300 K. Determine the net radiation through the glass.
