A bird is flying over a swimming pool at a height of `2m` from the water surface. If the bottom is perfectly plane reflecting surface and depth of swimming pool is `1m,` then the distance of final image of bird from the bird itself is `mu_w=4//3`

A swimming pool appears to be 6 m deep. Refractive index of water with respect to air, n_w = 4//3 . The real depth of the swimming pool is

A bird is flying 3m above the surface of water. To a fish underwater, the height of the bird from the water surface appears to be

What is the real depth of a swimming pool when its bottom appears to be raised by 1 m ? Given refractive index of water is 4//3 .

A girl sees through a circular glass slab (refractive index 1.5 ) of thickness 20 mm and diameter 60 cm to the bottom of a swimming pool. Refractive index of water is 1.33 . The bottom surface of the slab is in contact with the water surface. The depth of swimming pool is 6m. The area of bottom of swimming pool that can be seen through the slab is approximately -

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 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 fish lies at the bottom of a 4 m deep water lake. A bird flies 6m above the water surface and refractive index of water is 4//3 . Then the distance between
