The equiconvex lens has focal length f. ...

The equiconvex lens has focal length f. If is cut perpendicular to the principal axis passin through optical centre, then focal length of each half is

A

`(f)/(2)`

B

f

C

`(3f)/(2)`

D

2f

Text Solution

Verified by Experts

The correct Answer is:
D
If the equicenvex lens is cut along optical axis i.e., perpendicular to principle axis then focal length of each piece is double the focal length of original lens.
