What is the light reflected from a mineral surface called?

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. Diffuse reflection is when light hits an object and reflects in lots of different directions.
