In a lake, a fish rising vertically to the surface of water uniformly at the rate of 3 m/s, observes a bird diving vertically towards the water at the rate of 9 m/s. The actual velocity of the dive of the bird is (given, refractive index of water = 4/3)

A fish rising vertically up towards the surface of waterwith speed 3ms^(-1) observes a bird diving vertically down towards it with speed 9ms^(-1) The actual velocity of bird is (Given mu_ water =4/3

    A diver under water sees a bird in air, vertically above him. If the actual, height of the bird above the water surface is 'h' , then does it appear at the same height 'h' to the diver ? Explain giving reasons. If mu_(w) is the refractive index of water, find the shift in the bird's position as observed by the diver.

    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 bird in air looks at fish vertically below it and inside water in a tank. If the distances of the fish as estimated by the bird is hx and that of bird as estimated by the fish is h_(2) , then the refractive index of liquid 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 )
