Assertion : A concave mirror and convex lens both have the same focal length in air. When they are submerged in water, they will have same focal length.
Reason refractive index of water is smaller than be refractive index of air.

A concave mirror and a convex lens are of the same focal length in air. When they are immersed in water

In these question, a statement of assertion followed by a statement of reason is given .Choose the correct answer out of the following choices: Assertion and reason both are correct statements and reason is correct explanation for assertion. Assertion and reason both are correct statements but reason is not correct explanation for assertion. Assertion is correct statement but reason is wrong statement. Assertion is wrong statement but reason is correct statement. Assertion: A concave and convex lens both have the same focal length in air. When they both have the same focal length in air. When they are submerged in water they will have the same focal length. Reason: The refractive index of water is smaller than the refractive index of air.
