A fish in water sees an object which is `24cm` above the surface of water. The height of the object above the surface of water that will appear to the flash is `(mu=4//3)`

What portion of ice floats above the surface the water?

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

An under water swimmer is at a depth of 12 m below the surface of water. A bird is at a height of 18 m from the surface of water, directly above his eyes. For the swimmer the bird appears to be at a distance from the surface of water equal to (Refractive Index of water is 4/3)

A point source is placed at a depth h below the surface of water (refractive index = mu ). The medium above the surface of water is air from water.
