Q. Define: optic axis of a crystal.
In a double refracting crystal there is a particular direction in which both the rays travel with same velocity. This direction is called as optic axis.
The refractive index is similar for both rays and there is no double refraction along this direction.
A ray of light is incident on one of the faces of a parallel sided glass slab at an angle of incidence 510 31' of thickness 0.12 m . Evaluate the lateral shift produced given refra
