Opacity is the measure of impenetrability to electromagnetic or other kinds of radiation, especially visible light. In radiative transfer, it describes the absorption and scattering of radiation in a medium, such as a plasma, dielectric, shielding material, glass, etc. An opaque object is neither transparent (allowing all light to pass through) nor translucent (allowing some light to pass ...

Opacity or opaque means something that is difficult to see through or perceive. It can also mean: Opacity (optics), the degree to which light is blocked. Opaque context, a linguistic context in which it is not possible to substitute co-referential terms while guaranteeing the preservation of truth values. Opaque data, in computer programming ...

is the intensity of light remaining at distance x. is the initial intensity of light, at. For a given medium at a given frequency, the opacity has a numerical value that may range between 0 and infinity, with units of length 2 /mass. Opacity in air pollution work refers to the percentage of light blocked instead of the attenuation coefficient ...

Optical window. Rough plot of Earth's atmospheric transmittance (or opacity) to various wavelengths of electromagnetic radiation, including visible light. The optical window is a range of wavelengths that are not blocked by the earth's atmosphere. The window runs from around 300 nanometers ( ultraviolet-B) up into the range the human eye can ...

Measurements made at or near solar noon when the sun is not obstructed by clouds. Peaks indicate smoke, dust and smog. Saharan dust events are measured each summer. In physics, optical depth or optical thickness is the natural logarithm of the ratio of incident to transmitted radiant power through a material. Thus, the larger the optical depth ...

Transparency and translucency. Dichroic filters are created using optically transparent materials. In the field of optics, transparency (also called pellucidity or diaphaneity) is the physical property of allowing light to pass through the material without appreciable scattering of light. On a macroscopic scale (one in which the dimensions are ...

Opacity is the state of being impenetrable to light. An opaque object is neither transparent (allowing all light to pass through) nor translucent (allowing some light to pass through). When light strikes an interface between two substances, some of the light is reflected, some is absorbed, and the rest is transmitted (see also refraction).

Opacity or opaque may refer to:. Impediments to (especially, visible) light: Opacities, absorption coefficients Opacity (optics), property or degree of blocking the transmission of light Metaphors derived from literal optics: In linguistics: Opaque context, a term to describe the linguistic context of co-referential terms; Phonological opacity, a term in phonology
