certain species of fish is startled whenever it sees another animal 20 cm away, quickly running away. A fish of this species is in a cubic aquarium 5 cm away from the inside of the glass, while a person approaches to observe it more closely. The glass has n = 1.55 and is 3 cm thick. Assume that the person moves facing the fish and that the refractive index of water is 1.33. There is a first image of the person produced by refraction in the glass, and this image in turn functions as an object to produce a second image by refraction in water. (a) When the fish is startled and runs away, how far from the water/glass

(a) When the fish is startled and runs away, how far from the water/glass interface should the first image be?
(b) How far from the outside surface of the aquarium is the person when this happens? *
