In a pond of water, a flame is held 2 m above the surface of the water. A fish is at depth of 4 m from the water surface. Refractive index of water is `(4)/(3)`. The apparent height of the flame from the eyes of fish is -

The radius of the light circle observed by a fish at a depth of 12 meter is (refractive index of water = 4/3)

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

A swimmer is 12 m below the water surface. 18 cm above the water surface, right above the swimmer's eye, three is a bird. Refractive index of water is (4)/(3) . Calculate the apparent height of the bird from water surface as seen by the swimmer.

A fish lies at the bottom of a 4 m deep water lake. A bird flies 6m above the water surface and refractive index of water is 4//3 . Then the distance between

A fish lies at the bottom of a 4 m deep water lake. A bird flies 6m above the water surface and refractive index of water is 4//3 . Then the distance between

A fish lies at the bottom of a 4 m deep water lake. A bird flies 6m above the water surface and refractive index of water is 4//3 . Then the distance between

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 )

A man observe a fish at a depth of 6 cm from the surface of water in a pond. To hunt the fish, at what depth will he have to through the spear? Refractive index of water = (4)/(3) .

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
