If a convex lens is immersed in water, then its focal length

If the lens is placed in water instead of air, how does its focal length change?

Assertion : When a convex lens (mu_(g) = 3//2) of focal length f is dipped in water, its focal length become (4)/(3)f Reason : The focal length of convex lens in water becomes 4f.
