MCQ
The ray diagram could be correct

Image

  • A
    (a) If $n_1=n_2=n_g$
  • B
    (b) If $n_1=n_2$ and $n_1
  • ✓
    (c) If $n_1=n_2$ and $n_1>n_g$
  • D
    (d) Under no circumstances
✓

Answer

Correct option: C.
(c) If $n_1=n_2$ and $n_1>n_g$
(c) If $n_l>n_g$ then the lens will be in more denser medium. Hence its nature will change and the convex lens will behave like a concave lens.
