Question

What is the property of mineral exhibited by pyrite wherein it reflects light and with a metallic look?

Answer 1

Answer:

Luster describes the reflection of light off a mineral's surface. Mineralogists have special terms to describe luster. One simple way to classify luster is based on whether the mineral is metallic or non-metallic. Minerals that are opaque and shiny, such as pyrite, have a metallic luster

Answer 2

Lustre is the property of mineral exhibited by pyrite wherein it reflects light and with a metallic look.

• Lustre is the light refraction of a mineral's surface. Meteorologists use the term "lustre" to describe the look of minerals.

• The mineral's metallic or non-metallic nature is one straightforward approach to classify lustre. Minerals that have a metallic gleam, such as pyrite, are opaque and lustrous. Quartz, for example, has a non-metallic shine.

• Pyrite is a vivid metallic lustre brass-yellow mineral. It is the most prevalent sulphide mineral, with a chemical composition of iron sulphide (FeS2).

• The lustre of a mineral's surface refers to how it reflects light. It's important to distinguish shine from colour since they're not the same thing. A mineral defined as "bright yellow" is described in terms of lustre ("shiny") and colour ("yellow"), which are two distinct physical qualities.

• The term "metallic lustre" refers to the sheen of polished metal. Chrome, steel, titanium, copper, and brass, as well as a variety of other minerals, all have a metallic gleam. The most frequent nonmetallic lustre on  the mineral's surface is glassy, which means it reflects light in the same way as glass does.
