The back wall of the home aquarium is a mirror that is distance cm away from the front wall. The walls of the tank are thin, allowing the fish to swim midway between the front and back walls and be viewed by a person looking through the front wall. The index of refraction of air (nair) is 1.000 and the index of refraction of water (nwater) is 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.
