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).
Luster
A ray of light which strikes the surface is called incident ray and a surface which is reflected is called a reflected ray
When light bounces of a shiny surface, such as a mirror, this is called specular reflection.(Diffuse reflection is when light bounces of a rough surface, such as a wall. You can tell it's a rough surface because you can't see your reflection.)
Each ray of light is reflected according to the rules for a regular surface. But, because the surface is irregular, the direction of the reflected ray will vary from one point to another. This is called scattering.
The light which enters is called the incident ray and the reflected light is called the reflected ray.
Reflected ray
Luster
Surface reflection is either specular or diffuse.
A ray of light which strikes the surface is called incident ray and a surface which is reflected is called a reflected ray
Luster
It is called the equalight
A line of reflection is a reflected line, often off of a mirror. If a flashlight sends a beam of light at a mirror (the light is called the incident beam), the angle at which it hits the mirror will equall the angle at which the reflected beam of light (called the reflected beam), exits the mirror. This is called the Law of Reflection. This is why light is reflected from a mirror at the same angle at which light struck its surface.

It is the reflectivity of the surface. However, it is important to note that the reflected fraction depends on the wavelength of the incident light.
incident ray-the light ray striking a reflecting surface is called the incident ray. reflected ray-the light ray obtained after reflection from the surface, in the same medium in which the incident ray is travelling , is called the reflected ray.
This is called the "albedo." It is the ratio of reflected light compared to incident light, and depends on the surface material and its condition (e.g. snow, grassland).
Light can be reflected because it bounces off a surface at an angle.
Each ray of light is reflected according to the rules for a regular surface. But, because the surface is irregular, the direction of the reflected ray will vary from one point to another. This is called scattering.
