Two identical glass `(mu_(g)=3//2)` equi- convex lenses of focal length f each are kept in contact. The space between the two lenses is also filled with water `(mu_(g)=4//3).` The focal length of the combination is

A

f/3

B

f

C

(4f)/(3)

D

(3f)/(4)

Text Solution

Verified by Experts

The correct Answer is:
D
Using combination of lenses, we get
The focal length of the combination `rArr f_("eq")=(3f)/(4)`
