DOUBLE REFRACTION OF CALCITE<br />
Calcium Carbonate (CaCO3)<br />
Double refraction occurs when a ray of light enters the crystal it is split into fast and slow beams. As these two beams exit the crystal they are bent into two different angles because the angle is affected by the speed of the beams.
