The back wall of a home aquarium is a mirror that is a distance of 30.0 cm away from the front wall. The walls of the tank are negligibly thin. A fish, swimming midway between the front and back walls, is being viewed by a person looking through the front wall. The index of refraction of air isnair= 1.000 and that of water isnwater= 1.333.
(a) Calculate the apparent distance between the fish and the front wall.
(b) Calculate the apparent distance between the image of the fish and the front wall.
