Question
When a light ray refracts through a prism the incident ray is _____ to the emergent ray.
- Parallel
- Perpendicular
- Not parallel
- Coincident
Hint:
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.
