Q. 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. $\mu_{2} > \mu_{1} > \mu_{3}$. A wide, parallel beam of light is incident on the lens from the left. The lens will give rise to

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

(d) As $\mu_{2} > \mu_{1},$ the upper half of the lens will become diverging
As $\mu_{1} > \mu_{3}$, the lower half of the lens will become converging
