opacity1. the state or quality of being opaque 2. an opaque object or substance 3. Physics Photog the ratio of the intensity of light incident on a medium, such as a photographic film, to that transmitted through the medium 4. Logic Philosophy the property of being an opaque context opacity (oh-pass -ă-tee) A measure of the ability of a gaseous, solid, or liquid body to absorb radiation. It is the ratio of the total radiant energy received by the body to the total energy transmitted through it. For gaseous material of a particular chemical composition, opacity depends on both temperature and density. Various processes contribute to the opacity: energy absorption by electrons bound to an atom or ion, allowing them to jump to a higher level or to escape from the atom as free electrons (bound-bound or bound-free absorption); absorption by free electrons (free-free absorption); scattering of photone of radiation by free electrons or atoms (Compton scattering); absorption of γ-ray photons by ambient ‘gas' photons (photon-photon absorption). The negative hydrogen ion, H–, is a particularly important source of opacity in a star like the Sun, and the solar opacity is seen to drop rapidly to zero at the Sun's limb.OpacityQuality of being impenetrable by light; not reflecting light, or transmitting light, neither transparent nor translucent.opacity[ō′pas·əd·ē] (optics) The light flux incident upon a medium divided by the light flux transmitted by it. opacityThe quality of being opaque, as the capacity of a paint to cover or obliterate a background over which it is applied.opacityBeing "opaque," which prevents light from shining through. For example, in an image editing program, the opacity level for some function might range from completely transparent (0) to completely opaque (100).opacityenUK
opacity [o-pas´ĭ-te] 1. the condition of being opaque.2. an opaque area.o·pac·i·ty (ō-pas'i-tē), 1. A lack of transparency; an opaque or nontransparent area. 2. On a radiograph, a more transparent area is interpreted as an opacity to x-rays in the body. 3. Mental dullness. [L. opacitas, shadiness] opacity Medtalk A clouded or opaque area. See Corneal opacity. o·pac·i·ty (ō-pas'i-tē) 1. A lack of transparency; an opaque or nontransparent area. 2. On a radiograph, a more transparent area is interpreted as an opacity to x-rays in the body. 3. Mental dullness. [L. opacitas, shadiness]opacity The condition of a tissue or structure which is not transparent, or being opaque. The location of an opacity within the eye can be determined with a slit-lamp. It can also be determined using an ophthalmoscope and asking the patient to look up or down. If the opacity moves very little, or not at all, it is situated in the lens. If the opacity moves in the same direction as the eye it is situated in front of the lens and if it moves in the opposite direction it is situated in the vitreous humour. See cataract; muscae volitantes; corneal ulcer.o·pac·i·ty (ō-pas'i-tē) 1. On a radiograph, a more transparent area is interpreted as an opacity to x-rays in the body. 2. A lack of transparency.
