A small fish, 0.4m below the surface of a lake, is viewed through a simple converging lens of focal length 3m. The lens in kept at 0.2m above the water surface such that the fish lies on the optical axis of the lens. Find the image of the fish seen by the observer. The refractive index of water is `4//3`.
