absorption a process in which one substance permeates another
absorption spectrum the spectrum of electromagnetic radiation that has passed through a medium that absorbed radiation of certain wavelengths
absorptive having the power or tendency to soak up something
absorptivity (physics) the property of a body that determines the fraction of the incident radiation or sound flux absorbed or absorbable by the body
absorptance a measure of the rate of decrease in the intensity of electromagnetic radiation (as light) as it passes through a given substance; the fraction of incident radiant energy absorbed per unit mass or thickness of an absorber
absorption band a dark band in the spectrum of white light that has been transmitted through a substance that exhibits absorption at selective wavelengths
absorption coefficient a measure of the rate of decrease in the intensity of electromagnetic radiation (as light) as it passes through a given substance; the fraction of incident radiant energy absorbed per unit mass or thickness of an absorber
absorption factor (physics) the property of a body that determines the fraction of the incident radiation or sound flux absorbed or absorbable by the body
absorption indicator an indicator used in reactions that involve precipitation
absorption unit a unit for measuring absorption
