a measure of the ability of a material to absorb radiation, equal to the internal absorptance of a homogeneous layer of the material under conditions in which the path of the radiation has unit length and the boundaries of the layer have no influence
absorptivity in American English
(ˈæbsɔrpˈtɪvɪti, -zɔrp-)
noun
Physics
the property of a body that determines the fraction of incident radiation absorbed or absorbable by the body
Word origin
[1860–65; absorptive + -ity]This word is first recorded in the period 1860–65. Other words that entered Englishat around the same time include: calibrate, metric system, mutualism, pop-up, raider-ity is a suffix used to form abstract nouns expressing state or condition. Other wordsthat use the affix -ity include: Latinity, civility, jollity
