The term for an item that blocks and reflects light is "mirror." Mirrors have a reflective surface that bounces light off it, allowing us to see our reflection.
The term for the way a mineral reflects light is known as its "luster." Luster describes how light interacts with the surface of a mineral, with terms such as metallic, vitreous, pearly, or dull used to categorize the type of luster a mineral possesses.
The term is "albedo," which is a measure of the reflectivity of a surface or body, indicating how much incoming light is reflected back. A high albedo means more light is reflected, while a low albedo means more light is absorbed.
The phenomenon you are referring to is called "back reflection" or "back glare". This occurs when acrylic sheeting absorbs and then reflects light back towards the source, causing visibility issues or glare.
The term for producing light without heat is luminescence.
The term used to refer to a quantum of light is a photon.
Reflected light!
lustre
The term that describes how a mineral reflects light from its surface is luster. Luster refers to the way light interacts with the surface of a mineral, giving it a shine or reflective quality. Minerals can have metallic, vitreous (glassy), pearly, or dull lusters, among others.
The term for the way a mineral reflects light is known as its "luster." Luster describes how light interacts with the surface of a mineral, with terms such as metallic, vitreous, pearly, or dull used to categorize the type of luster a mineral possesses.
When a mineral reflects light, it can have a metallic luster, which gives it a shiny appearance like metal. Non-metallic luster refers to a dull or earthy appearance of a mineral. Brilliant luster is a term used to describe a mineral that reflects light in a very bright and sparkly way, often seen in gems like diamonds.
The term is "albedo," which is a measure of the reflectivity of a surface or body, indicating how much incoming light is reflected back. A high albedo means more light is reflected, while a low albedo means more light is absorbed.
The term for how a mineral reflects light from its surface is luster. Luster describes the way light interacts with the surface of a mineral, with common types including metallic, vitreous (glassy), pearly, and silky.
The term you're looking for is "luster." It refers to how light reflects off the surface of an object, giving it a shiny or dull appearance.
The way a surface reflects light is called its reflectance. This term describes how much light is reflected off the surface compared to how much is absorbed or transmitted. Reflectance can vary depending on factors such as surface texture, color, and angle of incidence.

This is called the luster of the mineral.The luster of a mineral is the way its surface reflects light. Most terms used to describe luster are self-explanatory: metallic, earthy, waxy, greasy, vitreous (glassy), adamantine (or brilliant, as in a faceted diamond).
