Prove that angle of incidence is equal to angle of emergence

1.	Prove that angle of incidence is equal to angle of emergence
Answer» Answer: The light ray is refracted out of the GLASS slab at the surface CD ALONG the path GH. The angle of incidence at this surface is ∠r2. The light ray EMERGES out of the slab forming ∠e as angle of emergence. Hence, angle of incidence EQUALS angle of emergence
