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).
Corundum is a crystalline form of aluminium oxide (Al 2 O 3) typically containing traces of iron, titanium, vanadium, and chromium. [3] [4] It is a rock-forming mineral.It is a naturally transparent material, but can have different colors depending on the presence of transition metal impurities in its crystalline structure. [7]
In other words, a translucent material is made up of components with different indices of refraction. A transparent material is made up of components with a uniform index of refraction. [1] Transparent materials appear clear, with the overall appearance of one color, or any combination leading up to a brilliant spectrum of every color.
Real-world subsurface scattering of light in a photograph of a human hand Computer-generated subsurface scattering in Blender. Subsurface scattering (SSS), also known as subsurface light transport (SSLT), [1] is a mechanism of light transport in which light that penetrates the surface of a translucent object is scattered by interacting with the material and exits the surface potentially at a ...
A classical element referred to as the Fifth Element in ancient and medieval times. It is believed to be the material that fills the region of the universe beyond the terrestrial sphere. This belief goes as far back as Plato's Timaeus, where it is said that "there is the most translucent kind which is called by the name of aether (αἰθήρ ...
Translucent fluorapophyllit-(K) crystal and stilbite, from Jalgaon District, Maharashtra, India Deep green isolated fluorite crystal showing cubic and octahedral faces, set upon a micaceous matrix Fabianite
Obsidian talus at Obsidian Dome, California Polished snowflake obsidian, formed through the inclusion of cristobalite crystals. The Natural History by the Roman writer Pliny the Elder includes a few sentences about a volcanic glass called obsidian (lapis obsidianus), discovered in Ethiopia by Obsidius, a Roman explorer.
