The back wall of a home aquarium is a mirror that is a distance of 32.0 cm away from the front wall. The walls of the tank are negligibly thin. A sh, 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 is nair = 1.000 and that of water is nwater = 1.333. (3) Calculate the apparent distance between the sh and the front wall. (b) Calculate the apparent distance between the image of the sh and the front wall. (a) d'= n v (b) d'= n v
