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 $\mathrm{O}_2$.
