absorptivity

Usually the difference in absorptivity is relatively small (parts per thousand).

The absorptivity quoted in such cases is being calculated by:

The keyhole leads to a sudden increase in absorptivity quickly deepening the hole.

At any given wavelength the absorptivity of the atmosphere will be equal to the emissivity.

The absorptivity is a measure of how strongly a molecule absorbs light at a particular wavelength.

The absorber plates in modern panels can have an absorptivity of more than 93%.

Average and overall absorptivity and emissivity data are often given for materials with values which differ from each other.

The included in the 2-element equivalent circuit is consistent with the earlier calculation of absorptivity, which gives .

With spectrophotometric data the molar absorptivity (or emissivity) values should all be positive.

As a result, the molar absorptivity in the near IR region is typically quite small.

High absorptivity in the 300-400 nm range.

In some cases, emissive power and absorptivity may be defined to depend on angle, as described below.

For example, white paint is quoted as having an absorptivity of 0.16, while having an emissivity of 0.93.

A closely related concept is molar absorptivity.

On a microscopic scale dendrites form on the surface finish, which trap light and increase absorptivity.

In science, the term absorptivity (or absorptance) may refer to:

The absorptivity is the ratio of the energy absorbed by the wall to the energy incident on the wall, for a particular wavelength.

The absorptivity coefficient units are dependent on the pathlength and concentration units.

Quantum dots have very sharp wavelength, high molar absorptivity and quantum yield.

Absorptivity, reflectivity, and emissivity of all bodies are dependent on the wavelength of the radiation.

Sails can be made of a crystalline dielectric, such as aluminum oxide, having extremely high strength and low optical absorptivity.

The sensitivity of these techniques can however be poor due to the low molar absorptivity of the analytes.

The absorption cross-section is closely related to molar absorptivity and mass absorption coefficient.

Moreover, the water vapour continuum absorptivity, molecule for molecule, decreases with pressure decrease.

It also serves to demonstrate that the depth of the photosphere of a star is highly dependent upon the absorptivity of its environment.
