Refractive index of Minerals

When a ray of light passes from air into a denser medium such as glass, it gets refracted. In the glass the light travels with a lesser velocity than in air and deviates from its previous path. The amount of deviation depends on the angle of incidence and the relative velocity of light in the …

Chemical Properties of Minerals

The chemical properties of the minerals depend on the chemical properties of the elements and compounds present in it. Moreover, the components of a mineral form a specific crystalline structure and thus result in definite chemical composition. The properties which are related directly to the chemical composition of the minerals are isomorphism, polymorphism, and pseudomorphism. …
