What “opacity” means

Wiktionary · Wikipedia

opacity/oʊˈpæsɪtiː/

  • nounThe state or quality of being opaque, not allowing light to pass through
Full entry on Wiktionary →

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 nor translucent. When light strikes an interface between two substances, in general, some may be reflected, some absorbed, some scattered, and the rest transmitted.
