The fraction of incident radiation that is absorbed by matter.

Absorptivity may be a function of wavelength and/or direction, and is related to the emissivity of the region by Kirchhoff's law. The absorptivity is identically equal to unity for blackbodies and is independent of wavelength for gray bodies.

The fraction of incident radiation that is absorbed by matter.
