A diverging lens with magnitude of focal length `25 cm` is placed at a distance of `15 cm` from a converging lens of magnitude of focal length `20 cm`. A beam of parallel light falls on the diverging lens. The final image formed is.

A

Real and at a distance of 6 cm from the convergent lens

B

Real and at a distance of 40 cm from convergent lens

C

Virtual and at a distance of 40 cm from convergent lens

D

Real and at distance of 40 cm from the divergent lens

Text Solution

Verified by Experts

The correct Answer is:
B
Image formed by first lens is `I_(1)` which is 25 cm left of diverging lens
For second lens u = 40 cm (i.e. at 2F) so final image will be 40 cm right of converging lens . Image will be real
