Two diverging lenses are kept as shown in figure. The final image formed will be

A

virtual for any value of `d_1 and d_2`

B

real for any value of `d_1 and d_2`

C

virtual or real depends on `d_1 and d_2` only

D

virtual or real depends on `d_1 and d_2` and also on the focal lengths of the lens

Text Solution

Verified by Experts

The correct Answer is:
A
`1/F=1/(f_1)+1/(f_2)-d/(f_1f_2)`
`f_1 and f_2` both are negative. Hence, F is also
negative. Object is real so combined lens (having
negative focal length ) will always make, its virtual
image.
