WebThe emissivity of a surface is defined as the ratio of the radiation emitted by the surface to the radiation emitted by a blackbody at the same temperature. Thus, 0 ≤ε≤1 Emissivity is a measure of how closely a surface approximate a blackbody, ε blackbody = 1. The emissivity of a surface is not a constant; it is a function of temperature ...
