Emissivity

Emissivity

The efficiency of a body's ability to absorb and reemit radiation compared to the emissivity of a blackbody at the same temperature. Emissivity ranges from 0 to 1, with one being a blackbody and less than 1 for all other materials. All bodies with a temperature above 0 K emit radiation.
