Question

When a white light refracts out through a rectangluar glass slab how are the emergent Ray and incident Ray related to each other​

Answer 1

Answer: angle i = angle e

Explanation: In case of refraction through a rectangular glass slab, the incident and emergent rays are parallel to each other because the angle of emergence ∠e is equal to the angle of incidence ∠i, i.e. ∠e = ∠i.

Hope this helps you!!

Answer 2

Answer:

angle e = angle i
