See Fig. and answer the following question.
a. Find apparent height of the bird.
b. Find apparent depth of the fish.
c. At what distance will the bird appear to the fish ?
d. At what distance will the fish appear to the bird?

Text Solution

Verified by Experts

a. Here bird is an object and fish is an observer. Hence, apparent height observed by the fish
`d_B^(')=d/n_("rel")=d/((n_("air")/n_("water")))rArrd_B^(')=36/(1/((4/3)))=36/(3//4)=48m`
b. Here the fish is an object and the bird is an observer . Hence, apparent height observed by the bird
`d_F^(')=d/n_("rel")=d/((n_("water")/n_("air")))rArrd_F^(')=36/(4//3)=27m`
c. For the fish, the bird will be observed at a distance `d_B^(')` from the fish: `d_B=36+48=84m`
d. For the bird, the fish will be observed at a distance `'d_F'` from the bird: `d_F= 27+36=63m`

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 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

A diver D is still under water ( mu = (4)/(3)) at a depth d = 10 m . A bird is diving along line AB at a constant velocity in air. When the bird is exactly above the diver he sees it at a height of 50 m from himself and velocity of the bird appears to be inclined at 45° to the horizontal. At what distance from the diver the bird actually hits the water surface.
