Webthe tendency of a mineral break along flat, parallel surfaces cleavage planes are surfaces of weak chemical bonding between repeating parallel layers of atoms in a crystal hardness … WebAs a result, the refractive index also varies with direction when light passes through an anisotropic crystal, giving rise to direction-specific trajectories and velocities. Perhaps one of the most dramatic demonstrations of double refraction occurs with calcium carbonate (calcite) crystals, as illustrated in Figure 2.
WebCrystallographic Origins of Birefringence. The property called birefringence has to do with anisotropy in the binding forces between the atoms forming a crystal, so it can be visualized as the atoms having stronger "springs" holding them together in some crystalline directions. A useful situation with mineral crystals occurs when there are two distinct indices of … WebOxides are compounds that consist of what 2 things. oxygen and another element, usually a metal.

Following is a qualitative explanation of the phenomenon. The simplest type of birefringence is described as uniaxial, meaning that there is a single direction governing the optical anisotropy whereas all directions perpendicular to it (or at a given angle to it) are optically equivalent.
