absorptivity"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.
Absorptivity The efficiency of radiation absorption.
Acclimatization The gradual adjustment of the body to new climatic or other environmental conditions, for example, the adjustment to low levels of oxygen at high altitudes.
absorptivityThe efficiency of radiation absorption.accretionThe growth of a precipitation particle by the collision of an ice crystal or snowflake with a supercooled liquid droplet that freezes upon impact.
Gray body A hypothetical body which absorbs some constant fraction, between zero and one, of all electromagnetic radiation incident upon it, which fraction is the absorptivity and is independent of wavelength. Compare to black body, white body.
