When a ray of light passes through a parallel slab of transport medium, then show that angle of incidence is equal to angle of emergence.

Angle of incidence is equal to angle of reflection

Angle of incidence is equal to the angle of reflection.

A ray of light passes through an equilateral glass prism, such that angle of incidence is equal to the angle of emergence. If the angle of emergence is 3//4 times angle of prism, calculate the refractive index of the glass prism.

When a ray of light enters a glass slab,then

The critical angle between a given trasparent medium and air is denoted by C.A ray of light in air medium enters this transprent meidum at an angle of incidence equal to polarising angle p.Deduce a relation for the angle of refraction in terms of C.

A ray of light falls on a mirror normally.What are the values of the angle of incidence and the angle of refelection?
