When a biconvex lens of glass having ref...

When a biconvex lens of glass having refractive index `1.47` is dipped in a liquid, it acts as a plane sheet of glass. This implies that the liquid must have refractive index.

A

Equal to that of glass

B

Less than one

C

Greater than that of glass

D

Less than that of glass

Text Solution

Verified by Experts

The correct Answer is:
A
If `(n)_("liquid") = (n)_("lens")` then lens behave as plane glass slab.
