| 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 |
A measure of the extinction due to absorption of monochromatic radiation as it traverses a medium. Usually expressed as a volume absorption coefficient, k v , with units of reciprocal length (ie, area per unit volume), but also as a mass absorption coefficient, k m , with units of area per unit mass. The two are related by k v = k m , where is the density of the absorber. See also absorption optical thickness.

| absorption coefficient |
A numeric measure of the amount of light energy that water itself and the dissolved and suspended substance within the water take up, which results in less energy or less light penetrating down into a water body. It can be measured for some or all of the wavelengths of a light ray and is reported by meter. It is an inherent optical property.

| absorption coefficient |
Light absorbed by a sample is attenuated at the rate I2/I1 = e-ab where I1 is the initial radiant power, I2 is the power after traversing a pathlength b, and a is called the absorption coefficient.
