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

Options

A. A single convergent beam
B. Two different convergent beams
C. Two different divergent beams
D. A convergent and a divergent beam

Answer

D

Explanation

For `mu_(1) gt mu_(3)` , converging (lower half)
For `mu_(1) lt mu_(2)` , diverging (upper half).
