| emissivity |
The ratio of the power emitted by a body at a temperature T to the power emitted if the body obeyed Planck's radiation law. Strictly, emissivity should be qualified by the frequency, direction, and even polarization state of the emitted radiation. ...

| 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.
