A water tank is 4 m deep. A candle flame is held 6 m above the water level. For water, \[\mu =4/3\]. Where will the image of the candle flame be formed?

Answer:

                The image of candle flame is formed due to reflection from water surface and not by refraction. The water surface acts like a plane mirror. The virtual image of flame is formed 6 m below the water surface.
