WebThe emissivity coefficient is commonly indicated with the symbol ε. In reality, the emissivity of real objects is generally wavelength dependent and indicated with the … WebWhat is Emissivity? Emissivity is a measure of the efficiency in which a surface emits thermal energy. It is defined as the fraction of energy being emitted relative to that emitted by a thermally black surface (a black body). A black body is a material that is a perfect emitter of heat energy and has an emissivity value of 1. A material with ...
