Question

A ray of light travelling through air falls on the surface of a glass slabe and emerges out of it parallel to the incident ray .The angle of incidence is i and angle of reflection is r and angle of emergence is e. Find ratio of Sin i/ Sin e and refractive index of e and r​

Answer 1

Answer:

Sin I/Sin e=1

Because both the rays are emerged parallely

So the angle between them is 0
