Solution
The correct option is A absorption coefficient.
The change in energy as the wave passes through a layer is a constant of the material for a given wavelength and is called its absorption coefficient.Absorption coefficient is a measure of rate of decrease in the intensity of electromagnetic radiation as it passes through given substance, the fraction of incident radiant energy absorbed per unit mass or thickness of an absorber.
