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 block of mass 10 kg is attached to the end of a horizontal spring with spring constant k = 1200 Nm-1. The block is assumed to be sitting on a frictionless horizontal surface.
