A converging lens of focal length f is placed just above a water surface parallel to the surface without touching it. A point source of light S is placed inside the water vertically before the lens at a depth f from it. This arrangement will produce: A) a parallel beam of light converging from the lens. B) a real image of S in air C) a virtual image of S in water D) a virtual image of S in air?

Answer:
Introduction:
The given arrangement consists of a converging lens placed just above the water surface parallel to the surface without touching it. A point source of light S is placed inside the water vertically before the lens at a depth f from it.
Explanation:
The light rays from the point source S will travel in all directions in water. When they will reach the water-air interface, they will bend away from the normal and move towards the lens. The rays parallel to the principal axis of the lens will converge at a point called the principal focus.
Virtual image:
The lens will form a virtual image of the point source S in air. The virtual image will be formed on the same side of the lens as the object. The image will be erect, magnified and will be located at a distance greater than the focal length of the lens.
Reasoning:
The light rays coming out of the lens will again bend away from the normal at the air-water interface and move towards the observer's eye. The observer will see the virtual image of the point source S in air.
Conclusion:
Hence, the correct option is D) a virtual image of S in air.
