Absorption Coefficient definition

                   The absorption coefficient is defined as how easily energy or matter ( light, sound, particles ) passes through a medium or material. Absorption coefficient is measured by the units of reciprocal length. Absorption coefficient is also called as attenuation coefficient, linear attenuation coefficient. Absorption coefficient are different for different frequencies. Small absorption coefficient means medium is relatively transparent to the beam. Large absorption coefficient means beam is quickly passes through the medium. See also Beer- Lambert Law.
