A bird flies down vertically towards a water surface. To a fish inside the water, vertically below the bird, the bird will appear to (i) be farther away than its actual distance (ii) be closer than its actual distance (iii) move faster than its actual speed (iv) move slower than its actual speed

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

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 fish is vertically below a flying bird moving vertically down toward water surface. The bird will appear to the fish to be

A fish rising up vertically toward the surface of water with speed 3ms^(-1) observes a bird diving down vertically towards it with speed 9ms^(-1) . The actual velocity of bird is

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 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 )
