Chapter , Problem 12.16(choose chapter or problem)
The spectral distribution of the radiation emitted by a diffuse surface may be approximated as follows (a) What is the total emissive power? (b) What is the total intensity of the radiation emitted in the normal direction and at an angle of 30 from the normal? (c) Determine the fraction of the emissive power leaving the surface in the directions /4 /2.
