MCQ
Consider three converging lenses $L_1, L_2$ and $L_3$ having identical geometrical construction. The index of refraction of $\mathrm{L}_1$ and $\mathrm{L}_2$ are $\mu_1$ and $\mu_2$ respectively. The upper half of the lens $\mathrm{L}_3$ has a refractive index $\mu_1$ and the lower half has $\mu_2$. A point object $O$ is imaged at $O_1$ by the lens $L_1$ and at $O_2$ by the lens $L_2$ placed in same position. If $L_3$ is placed at the same place:
  • A
    There will be an image at $\mathrm{O}_1$
  • B
    There will be an image at $\mathrm{O}_2$
  • Both $A$ and $B$
  • D
    The only image will form away from $\mathrm{O}_2$.

Answer

Correct option: C.
Both $A$ and $B$

It rays are Passing through $\mathrm{m}_1$ then Image will be form at $"\mathrm{O}_1"$ and If rays are Passing through $\mathrm{m}_2$ then Image will be form at $"\mathrm{O}_2".$
