What is emissivity?
The ratio of energy emitted by an object to the energy emitted by a blackbody at the same temperature. The emissivity of an object depends upon its material and surface texture:a polished metal surface can have an emissivity around 0.2 and a piece of wood can have an emissivity around 0.95.
