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.
