For instance, some kinds of glass, while transparent in the visual range, are largely opaque to ultraviolet light. More extreme frequency-dependence is visible in the absorption lines of cold gases. Opacity can be quantified in many ways; for example, see the article mathematical descriptions of opacity.
Due to the lack of consistent terminology, research transparency has frequently been defined negatively by addressing non-transparent usages (which are part of questionable research practices).

Diffuse reflection - Generally, when light strikes the surface of a (non-metallic and non-glassy) solid material, it bounces off in all directions due to multiple reflections by the microscopic irregularities inside the material (e.g., the grain boundaries of a polycrystalline material or the cell or fiber boundaries of an organic material ...

A new cohort of ETFs called Active Non-Transparent ETFs, has been hitting headlines lately. ANT ETFs give active managers a chance to keep their investing methods under coverage to evade the front ...
This is opposed to keeping this information hidden which is "non-transparent". A practical example of transparency is also when a cashier makes changes after a point of sale; they offer a transaction record of the items purchased (e.g., a receipt) as well as counting out the customer's change.
The sheerness of a fabric is expressed as a numerical denier which ranges from 3 (extremely rare, very thin, barely visible) to 15 (standard sheer for stockings) up to 30 (semi opaque) until 100 ().
