WebNov 16, 2024 · It represents the ratio between the energy radiated from the material’s surface, and the energy radiated from another material referred to as a blackbody. A blackbody absorbs thermal radiation and emits it so well, it’s the standard to which all other surfaces are compared. The blackbody’s emissivity rating is the highest possible, at 1. WebEmissivity "E": The emissivity of a material (usually written ε or e) is the relative ability of its surface to emit energy by radiation.
