MCQ
The ray diagram could be correct
- AIf ${n_1} = {n_2} = {n_g}$
- BIf ${n_1} = {n_2}$ and ${n_1} < {n_g}$
- ✓If ${n_1} = {n_2}$ and ${n_1} > {n_g}$
- DUnder no circumstances
✓
Answer
Correct option: C.
If ${n_1} = {n_2}$ and ${n_1} > {n_g}$
c
(c) If ${n_l} > {n_g}$ then the lens will be in more denser medium.
(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.
