A Spherical Fish Bowl. A small tropical fish is at the center of a water-filled, spherical fish bowl 28 cm in diameter. Find the apparent position (distance between image and ball surface in algebraic value) of the fish to an observer outside the bowl (in the air). The effect of the thin walls of the bowl may be ignored. The refractive index of the water is nwoter = 1.33. (Give your answer in decimal using cm (centimeter) as unit)
