MCQ
When a ray of light from air enters a denser medium, it : ________ .
  • A
    Bends away from the normal
  • ✓
    Bends towards the normal
  • C
    Goes undeviated
  • D
    Is reflected back
✓

Answer

Correct option: B.
Bends towards the normal
The ray of light bends towards the normal.
Reason: As the speed of light decreases in the denser medium, it bends towards the normal.
