MCQ
A light ray remains unbent at the boundary when passing from one medium to another if the angle of incidence is:
- ✓$0^{\circ}$
- B$45^{\circ}$
- C$60^{\circ}$
- D$90^{\circ}$
✓
Answer
Correct option: A.
$0^{\circ}$
(a)
$0^{\circ}$
Explanation:
A ray incident normally on the surface between two media experiences no bending. In this case, both the angle of incidence and angle of refraction are $0^{\circ}$.
