Question

When a light ray refracts through a prism the incident ray is _____ to the emergent ray.

  1. Parallel
  2. Perpendicular
  3. Not parallel
  4. Coincident

hintHint:

In a prism, the refraction of light ve occurs at two inclined faces,

The correct answer is: Not parallel


     In a prism, the refraction of light ve occurs at two inclined faces, so the emergent ray is not parallel to the incident ray, but it is deviated towards the base of prism.
