Question

A convex lens kept in a medium with refractive index less than the refractive index of the lens behaves like

• A. Diverging lens
• B. Converging lens
• C. Plane mirror
• D. Concave mirror

Hint:

When the refractive index of the surrounding medium is less than that of the lens, the convex lens acts like a diverging lens, forming diverging rays.

Answer 1

The Correct Option is A

When a convex lens is placed in a medium with a lower refractive index than the lens, it behaves like a diverging lens. This is because the difference in refractive indices causes the lens to diverge light instead of converging it.
