Statement-1 : If a convex lens is kept in water, its convergent power increases.
Statement-2 : Focal length of lens depends on its refractive index w.r.t. surrounding medium.

A

Statement-1 is true, Statement-2 is true.
Statement-2 is correct explanation of Statement-1.

B

Statement-1 is true, Statement-2 is true, but Statement-2 is not a correct explanation of Statement-1.

C

Statement-1 is true, Statement-2 is false.

D

Statement-1 is fasle, Statement-2 is true.

Text Solution

Verified by Experts

The correct Answer is:
D

Statement-1 is fasle, but statement-2 is true. Focal length of a lense does depend on the refractive index of lens material w.r.t. the surrounding medium.
