A brid flies down vertically towards a water surface. To a fish inside the water, vertically below the bird, the bird will appear to

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)

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
