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

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

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

A fish in water (refractive index n ) looks at a bird vertically above in the air. If y is the height of the bird and x is the depth of the fish from the surface, then the distance of the bird as estimated by the fish is

A fish in water (refractive index n ) looks at a bird vertically above in the air. If y is the height of the bird and x is the depth of the fish from the surface, then the distance of the bird as estimated by the fish is

A tank's depth is 2d and the apparent depth of the liquid in the tank is 60 % its actual depth. What is the refractive index of the liquid with respect to air?

A bird views a fish at 3 m depth in water. Real depth of fish is ..... (Refraction index of water is 4/3 )

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 fish in a lake (refractive index 4//3 for water ) is viewed through a convex lens. From water surface, the lens is placed in air at half of the distance of the fish from the water surface, so that the image is formed at the fish itself. The focal length of the lens is how many times the depth of fish in water?
