A bird is flying up at an angle   sin¯¹ (3/5) with the horizontal. A fish in a pond looks at that bird. When it is vertically above the fish. The angle at which the bird appears to fly to the fish is (given refractive index of water - 4/3)

Expert Answer:

Here the bird is the object and the fish is the observer.
 
From point of view of fish:


y axis represents the vertically upward direction and x-axis gives the horizontal direction.
Hence the apparent height(vertical) observed by the fish:
