Question

A ray falls on a glass slab of thickness 6 cm making an angle 37 degrees with the surface as shown.The two surfaces of the slab are parallel to each other then prove

Answer 1

Answer:

In a glass slab opposite sides are parallel. The angle of refraction becomes the angle of incidence in the second face. The emergent ray bends in such a way that the angle of incidence becomes the angle of emergence. In this case the incident ray and the emergent ray will not be parallel to each other.
