Anisotropic minerals/interference

Anisotropic minerals/interference. Isotropic minerals: velocity of light same in all directions. 1 index of refraction Isometric crystal system Anisotropic minerals: velocity of light varies. Light split into two rays; vibrate perp. to each other 2 velocities, 2 indices of refraction.
