A bird in air looks at a fish vertically below it and inside water. h_(1) is the height of the bird above the surface of water and h_(2) , the depth of the fish below the surface of water. If refractive index of water with respect to air be mu , then the distance of the fish as observed by the bird is

An observer observer a fish moving upwards in a cylindrical container of cross section area 1 m^(2) filled with water up to a height of 5 m . A hole is present at the botton of the container having cross section areea 1//1000 m^(2) . Find out the speed of the image of fish observed by observer when the botton hole is just opened. (Given: The fish is moving with the speed of 6 m//s towards the observer, mu of water =4//3 )
