WebThe emissivity of a material (usually written ε) is the ratio of energy radiated by the material to energy radiated by a black body at the same temperature. It is a measure of a material's ability to absorb and radiate energy. A true black body would have an ε = 1 while any real object would have ε 1.Emissivity is a numerical value and does not have units. WebThe ratio varies from 0 to 1.
