Assertion: If a lens is immersed in a liquid its nature will change ie., convex will behave concave and vice-versa.
Reason: If both sides of a lens medium is same, then object can be placed on either side of the lens, image distance remains same

A

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

B

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

C

If Assertion is true but Reason is false.

D

If Assertion is false but Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
(d) Nature of lens will change only, if refractive index of liquid is more than that of material of lens.
