Definition of the noun absorption coefficient
What does absorption coefficient mean as a name of something?
- 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
The absorption coefficient α is a property of a material. It defines the extent to which a material absorbs energy, for example that of sound waves or electromagnetic radiation. Wallace Sabine was a pioneer of this concept in acoustics and defined the unit of the Sabin. A Sabin is defined as the absorption by a 1m square slab of perfectly-absorptive material.
