If a substance is behaving as convex lens in air and concave
lens in water then which one of the following is its refractive
index?

A

greater than air but less than water

B

greater than both air and water

C

smaller than air

D

almost equal to water

Text Solution

Verified by Experts

The correct Answer is:
A
When a lens is immersed in a medium whose refarctive index is greater than that of the lens, its nature changes. Here the lens changes its nature when immersed in water it means its refractive index is less than that of water.
