Isotropic and anisotropic minerals

Depending upon the optical properties, the minerals can be divided into two groups: (i) isotropic minerals and (ii) anisotropic minerals. Isotropic Minerals: In crystals belonging to the cubic system, the light travels with the same velocity in all directions and therefore each mineral has only one refractive index. Such minerals are called ”isotropic minerals”. Non-crystalline …
