See more. 2014-02-24 Overview of Absorption. I intend to write some text explaining the general process of absorption of sound in air (viscous effects, thermal conduction effects, and molecular relaxation processes). But, in the mean time, the interactive plot below works and allows for calculation of the absorption coefficient … absorption coefficient.

Several important optical terms, such as “absorbance” and “absorption coefficient,” are frequently used ambiguously in the current peer‐reviewed literature. Because these terms are important when deriving other quantities, such as the apparent quantum yield of photoproduction, ambiguity in the application of these concepts leads to results that are difficult or impossible to

In a similar manner, we can define αm = α/ρ, where ρ is the mass density, as the mass absorption coefficient, with corresponding modifications in all the other equations. Mass absorption and scattering coefficients When a narrow (collimated) beam passes through a volume, the beam will lose intensity to two processes: absorption and scattering. Mass absorption coefficient, and mass scattering coefficient are defined as 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; "absorptance equals 1 minus transmittance" absorption coefficient causes the film to absorb any multiple reflections of the light.
