(Denizbilim) absorption coefficient
a measure of the absorption of electromagnetic radiation as it passes through a specific substance; the fraction of incident radiation absorbed by unit mass or unit thickness
A measure of the amount of radiant energy, incident normal to a planar surface, that is absorbed per unit distance or unit mass of a substance
The amount of radiant energy absorbed per unit or path-length
The fraction of light absorbed per unit distance in a participating medium In SI units, this is specified as a fraction per meter In Radiance, the absorption is given separately for red, green, and blue
  A measure of the attenua­tion caused by absorption of energy that results from its passage through a medium   [After 2196]  Note 1:   Absorption coefficients are usually expressed in units of reciprocal distance   Note 2:   The sum of the absorption coefficient and the scattering coefficient is the attenuation coefficient
The factor by which photons are absorbed as they travel a unit distance through a material
A measure of the extinction due to absorption of monochromatic radiation as it traverses a medium Usually expressed as a volume absorption coefficient, kv, with units of reciprocal length (i e , area per unit volume), but also as a mass absorption coefficient, km, with units of area per unit mass The two are related by kv km, where is the density of the absorber See also absorption optical thickness
a number that is proportional to the "amount" of light removed from a sight path by absorption per unit distance
Electromagnetic radiation may be absorbed by an atom or a molecule Different atoms and molecules are likely to absorb different wavelengths of radiation For example the yellow wavelength at about 590 µm is easily absorbed, and emitted, by sodium vapour giving sodium street lamps their characteristic yellow colour The probability of a photon of electromagnetic radiation being absorbed when it encounters an atom or molecule is known as the absorption coefficient A value of 1 0 means a probability of 100% absorption and a value of 0 5 a probability of 50% absorption Cool objects such as interstellar dense clouds will contain molecules which will tend to absorb in the infra red region of the electromagnetic spectrum
A number characterizing the extent to which specified gamma (or X) rays transfer their energy to a material through which they pass The linear energy absorption coefficient is a measure of the energy transfer (or absorption) per unit thickness of material and is stated in units of reciprocal length (or thickness) The mass energy absorption coefficient is equal to the linear absorption coefficient divided by the density of the absorbing material; it is a measure of the energy absorption per unit mass See Attenuation coefficient
The fraction of sound energy that is absorbed at any surface It has a value between 0 and 1 and varies with the frequency and angle of incidence of the sound
A measure of the amount of radiant energy, incident normal to a planar surface, that is absorbed per unit distance or unit mass of a substance (Source: Carbon Dioxide Information Analysis Center, 1990)
(a): Value representing the ability of a body to absorb radiation in the wavelength A black body has an absorption factor = 1
In reference to a solar energy conversion devices, the degree to which a substance will absorb solar energy In a solar photovoltaic device, the factor by which photons are absorbed as they travel a unit distance through a material
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
a measure of the ability of particles or gases to absorb photons; a number that is proportional to the number of photons removed from the sight path by absorption per unit length
The energy of sound waves being taken in (entering) the surface of any material rather than being bounced off or reflected; usually given in octave bands Materials are rated in terms of their ability to absorb sounds
