| has gloss | (noun) the quality of being opaque to a degree; the degree to which something reduces the passage of light opaqueness, opacity |
| has gloss | eng: 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 through). When light strikes an interface between two substances, in general some may be reflected, some absorbed, some scattered, and the rest transmitted (also see refraction). Reflection can be diffuse, for example light reflecting off a white wall, or specular, for example light reflecting off a mirror. An opaque substance transmits very little light, and therefore reflects, scatters, or absorbs most of it. |

| has gloss | ara: العتامة هي قياس للااختراقية الأشعة الكهرومغناطيسية أو الأنواع الأخرى من الإشعاع، وخصوصًا الضوء المرئي. وفي الانتقال الإشعاعي (radiative transfer)، تصف العتامة امتصاص و تبعثر الإشعاع في الوسط، مثل البلازما، والعوازل الكهربائية، والدرع ضد الإشعاعات، والزجاج، إلخ. إن الجسم العاتم ليس شفافًا فيسمح للضوء بالمرور خلاله، أو شفيف (Translucent) فيسمح بمرور بعض الضوء خلاله. |

| has gloss | ita: A seconda della qualità della trasmissione della luce da parte di un minerale, esso verrà detto: * Trasparente. Descrive un minerale che trasmette la luce e attraverso il quale è possibile osservare un oggetto. Il quarzo e la calcite normalmente sono trasparenti. La maggior parte delle gemme ha un’elevata trasparenza e viene valutata dal punto di vista del valore economico in base proprio alla qualità della trasparenza. |

| has gloss | nor: Opasitet er et mål på «ugjennomsiktighet» for elektromagnetisk stråling, f. eks lys, i forskjellige materialer. Et stoff er opakt dersom det har høy opasitet. Når stråling treffer overgangen mellom to stoffer vil det kunne bli reflektert, transmittert eller absorbert. Et opakt materiale har lav transmisjon og største delen av strålingen blir enten absorbert eller reflektert. Opasiteten er avhengig av lysets bølgelengde (og dermed frekvens); Vanlig glass er transparent for synlig lys men opakt for ultrafiolett stråling. Opasiteten vil oftest også være avhengig av mediets temperatur og trykk. |

| has gloss | por: A opacidade é uma propriedade óptica da matéria, que apresenta diversos graus e características. Popularmente, um material é considerado "opaco" quando não permite a passagem da luz em proporções apreciáveis. Mais genericamente, e por uma abordagem mais formal em física, é a medida da impenetrabilidade a radiação eletromagnética ou outros tipos de radiação, incluindo a mais perceptível pelos humanos luz visível. |

| has gloss | slk: ::Opacita znamená aj všeobecne nepriesvitnosť. Opacita (lat. opacitas - zatienenie, tieň) je schopnosť látky (plynu) zoslabiť žiarenie všetkých vlnových dĺžok, ktoré ňou prechádza. Opacita vyjadruje mieru nepriesvitnosti látky a určuje sa podielom množstva žiarenia dopadajúceho na látku a prechádzajúceho látkou (absorpcia). Pri danej teplote opacita závisí od počtu častíc v objemovej jednotke. Vrstvy plynu s veľkou optickou hrúbkou majú opacitu väčšiu ako opticky tenké vrstvy. |
