Reradiate

Reradiate

*For other meanings of the term, see Reradiation.

An object that absorbs some amount of radiative energy, and then later emits that energy in the form of radiative energy is referred to as reradiating the absorbed energy.

The term is most often used in discussion of absorption of light or infrared radiation. In the normal process of thermal absorption and emission, the reradiated energy is emitted at a longer wavelength (i.e., lower energy).
