An object may be not transparent either because it reflects the incoming light or because it absorbs the incoming light. Almost all solids reflect a part and absorb a part of the incoming light. When light falls onto a block of metal , it encounters atoms that are tightly packed in a regular lattice and a " sea of electrons " moving randomly ...
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 ).

Such minerals are transparent or translucent, and have a high refractive index (of 1.9 or more). [2] Minerals with a true adamantine lustre are uncommon, with examples including cerussite, zircon, and cubic zirconia. [2]
Because it is often transparent and chemically inert, glass has found widespread practical, technological, and decorative use in window panes, tableware, and optics. Some common objects made of glass are named after the material, e.g., a "glass" for drinking, "glasses" for vision correction, and a "magnifying glass".
Such losses become particularly significant, for example, in metals at short (e.g. visible) wavelengths, and must be included in any description of the refractive index. Refraction, critical angle and total internal reflection of light at the interface between two media.
To give you a glimpse of how amazing this connection can be, here's a list of man-made objects that fit the bill. #1 Bird Safe Glass Every day, hundreds of birds die from flying into glass windows.
Transparent armor is a material or system of materials designed to be optically transparent, yet protect from fragmentation or ballistic impacts. The primary requirement for a transparent armor system is to not only defeat the designated threat but also provide a multi-hit capability with minimized distortion of surrounding areas.
