MCQ

Consider three converging lenses $L_1, L_2$ and $L_3$ having identical geometrical construction. The index of refraction of $L_1$ and $L_2$ are $\mu_1$ and $\mu_2$ respectively. The upper half of the lens $L_3$ 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 $O_1$
B
There will be an image at $O_2$
✓
A and B both
D
The only image will form away from $O_2$.

✓

Answer

Correct option: C.

A and B both

Explanation:

It rays are Passing through $m_1$ then Image will be form at "$O_1$" and If rays are Passing through $m_2$ then Image will be form at "$O_2$".
