A man stnading in a swimming pool looks at a stone lying at the bottom. The depth of the swimming pool is h. At what distance from the surface of water is the image of the stone formed? (Line of vision is normal, Refractive index of water is n)

A man standing in a swimming pool looks at a stone lying at the bottom. The depth of the swimming pool is h. At what distance from the surface of water is the image of the stone formed -

A man standing on the bottom. The depth o fthe swimming pool looks at a stone lying on the bootom. The depth of the swimming pool is equal to h . At what distance from the surafce of water is the image of the stone formed if the line of vision makes an angle theta with the normal to the surface?

A man in an empty swimming pool has a telescope focussed at 4o'clock sun. When the swimming pool is filled with water, the man observes the setting sun through telescope. If sunrises and sets at 6 o'clock, then refractive index of water is

A bird in air is at a height ‘y’ from the surface of water. A fish is at a depth ‘x’ below the surface of water. The apparent distance of fish from the bird is (The refractive index of water is n )

A stone S is on the bottom of a swimming pool. The depth of the lying pool is d and index of refraction of water is mu . What is the depth of the swimming pool visible to a normal eye ? Cheak the results with d=6ft and mu=1.5 .
