Assertion: Image of an object is of same size by a convex lens. If a glass slab is placed between object and lens, image will become magnified.
Reason: By inserting the slab, image may be real or virtual.

A

If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of the Assertion.

C

If both Assertion is true, but the Reason is false.

D

If both Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B
By inserting a slab between the lens and the
object, effective distance between object and lens
decrease. So, object now comes between F and
2F or between F and O.

In the first case, image is real and magnified and in
the second case it is virtual and magnified.
