A hollow double concave lens is made of very thin transparent material. It can be filled with air or either of two liquids `L_(1)` or `L_(2)` having refractive indices `n_(1)` and `n_(2)`, respectively `(n_(2) gt n_(1) gt 1)`. The lens will diverge parallel beam of light if it is filles with

A

air and placed in air

B

air and immersed in `L_(1)`

C

`L_(1)` and immersed in `L_(2)`

D

`L_(2)` and immersed in `L_(1)`

Text Solution

Verified by Experts

The correct Answer is:
d.
If the refractive index of the material of the lens is greater thatn the refractive index of the surrounding medium, then a concave lens would behave as a concave lens.
