Question

A ray of light travelling through air falls on the surface of a glass slab and emerges out of it parallel to the
incident ray. The angle of incidence i, angle of refraction in glass r and angle of emergence is e. Find the ratio of sin i/sin e and refraction index of glass in terms of e and r

Answer 1

Answer:

In refraction the ratio of Sin of Incidence(sin I) to the Sin of Emergence(sin e) is always constant...
