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

If a fish lies at the bottom of a 4 m deep water tank (mu = 4//3) and a bird is flying at a height of 6m above the water surface, then apparent distance at which the fish appears to the bird is

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 -

A pond appears to be 2.7 m deep. If the refractive index of water is 4/3 , find the actual depth of the pond.

A water pond appears to be 2*7m dep. If the refractive index of water is 4//3 , find the actual depth of the pond.

A pile 4m high driven into the bottom of a lake is 1m above the water . Determine the length of the shadow of the pile on the bottom of the lake if the sun rays make an angle of 45^@ with the water surface . The refractive index if water is 4/3 .
