Find out the following in the figure shown below :
(a) The apparent speed of the fish as observed by the bird
(b) The apparent speed of the bird as observed by the fish

Find out the following in the figure shown below : (a) The apparent distance of the fish from the surface as observed by the bird (b) The apparent distance of the bird from the surface as observed by the fish

A plane mirror is fixed at the bottom of a vessel as shown in the figure. Water of refractive index mu is filled up to a height h in the vessel. There is a fish at a height h//2 from bottom of vessel and there is a bird at a height h above the surface of water in the vessel. (a) Calculate apparent distance of bird as seen by the fish. (b) Calculate apparent distance of image of bird in mirror as seen by the fish. (c) Calculate apparent distance of fish as seen by the bird. (d) Calculate apparent distance of image of fish in the mirror as seen by the bird.

A bird in air looks at a fish directly below it inside in a transparent liquid in a tank. If the distance of the fish as estimated by the bird is h_1 and that of the bird as estimated by the fish is h_2, then the refractive index of the liquid is
