luster
The property of a mineral that shows how it reflects light is called luster. Luster can be described as metallic, glassy, pearly, silky, or dull.
The property of a mineral that shows the color of its powder is called streak. Streak is determined by rubbing the mineral against an unglazed porcelain plate to produce a colored powder. This color can sometimes be different from the color of the mineral itself.
The ability of a mineral to reflect light is known as its luster. Luster is a fundamental property used in mineral identification and classification. Minerals can exhibit various types of luster, such as metallic, vitreous (glassy), pearly, resinous, or dull, depending on their chemical composition and crystal structure. By observing the luster of a mineral, geologists can gather valuable information about its physical and chemical characteristics.
An echo reflects sound like a mirror reflects light, but it never physically appears or shows itself.
Yes, ultraviolet light can be used to identify willemite, a mineral that usually shows a green fluorescence under short-wave ultraviolet light. This fluorescence property is a key characteristic used in mineral identification.
The physical property that typically shows the greatest variation in minerals is color. Minerals can exhibit a wide range of colors due to variations in chemical composition, impurities, and light absorption.
The term for this that I've always heard is "streak".
Photo electric emission
because the light reflects off ofthe flower and shows its ture colors
Double refraction is when you can see through a mineral and it shows two images instead of one. Calite is the mineral that exhibits it. I linked a great website for this kind of stuff below.
It shows the Commutative property.
