Birefringence

Features Birefringence

Shows a light ray within a birifringent crystal and reflection and transmission at the surface towards air.Answers questions like:* Is the angle of reflection always the same as the angle of incidence?* What happens in case of perpendicular incidence?* Are the wavefronts always perpendicular to the direction of the ray?* How is the polarisation of the rays?* How is the power distributed between ordinary and extraordinary ray?* How does the direction of the optic axis influence all of this?
