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

Answer

D

Explanation

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.
