A double convex lens, made of a meterial of refractive index `mu_(1)`, is placed inside two liquids of refractive indices `mu_(2)` and `mu_(3)`, as shown. `mu_(2) gt mu_(1) gt mu_(3)`. A wide, parallel beam of light is incident on the lens from the left. The lens will give rise to.

Text Solution

Verified by Experts

The correct Answer is:
D

As given `u_(2) lt u_(1) gt u_(3)`
`because u_(2) gt u_(1) implies` lens act as a concave lens for upper half portion of lens & `u_(3) lt u_(1)`
`implies` Lower half portion act as a convex lens.
