  4. μ1>μ

A
μ1<μ

D
μ1μ
Solution
Verified by Toppr

Since, the given lens is a convex lens hence it should converge a parallel beam of light falling on it to a single focal point. However, since it is showing the exactly opposite behaviour, thus it is definitely placed in a medium of higher refractive index.
Thus, we conclude that μ1>μ
