What is the appearance of a mineral as it reflects light?

Luster is how the surface of a mineral reflects light.

When a mineral reflects light it appears shiny like polished metal What property of the mineral Does this describe?

Luster is the way that a mineral reflects light. There are two major types of luster; metallic and non-metallic luster. A mineral with a metallic luster is either shiny, because it reflects light like a polished piece of metal, or is dull- looking, because it reflects light like a metal rust or a metal tarnish.

What property of a mineral refers to the ability of the mineral to reflect light?

Luster is how a mineral reflects light. The terms metallic and nonmetallic describe the basic types of luster.

What does reflect light mean?

Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. This is called specular reflection. For a smooth surface, reflected light rays travel in the same direction.

What is a translucent mineral?

Translucent – light can pass through the mineral but is diffused so that images cannot be seen clearly; Transparent – light can pass through the mineral and images can be seen clearly. Variations of transparency (opaque hornblende, translucent biotite and transparent calcite)

Which of the following terms is used to describe the appearance of a mineral in transmitted light?

Luster refers to the general appearance or sheen of a mineral. It refers to the way in which a mineral reflects light.

What does luster tell you about a mineral?

Luster describes how a mineral appears to reflects light, and how brilliant or dull the mineral is. The terms used to describe luster are: Metallic (also known as splendent) Submetallic.

What property do minerals that glow under ultraviolet light display?

Fluorescence
Fluorescence is the property of a mineral to emit visible light when activated by ultraviolet light (UV). The light emitted by the lamps in this display reacts with certain chemical elements in the composition of the mineral and cause the mineral to glow.

What property of a mineral is a result of the reflection of visible light hence can be easily observed?

Luster. The luster of a mineral is the way that it reflects light.

How is the color of light reflected or absorbed?

Rather, the color is in the light that shines upon it and is ultimately reflected or transmitted to our eyes. We know that the visible light spectrum consists of a range of frequencies, each of which corresponds to a specific color. When visible light strikes an object and a specific frequency becomes absorbed,…

How are transparent materials used to transmit light?

Transparent materials are materials that allow one or more of the frequencies of visible light to be transmitted through them; whatever color (s) is/are not transmitted by such objects, are typically absorbed by them.

How does light affect the appearance of an object?

Any visible light that strikes the object and becomes reflected or transmitted to our eyes will contribute to the color appearance of that object. So the color is not in the object itself, but in the light that strikes the object and ultimately reaches our eye.

What happens when white light shines on an opaque object?

This will usually increase the internal energy of the particles. When white light shines on an opaque object, some wavelengths or colours of light are absorbed. These wavelengths are not detected by our eyes. The other wavelengths are reflected, and these are detected by our eyes.
