The apparent depth of an object submerged in water is less than its actual depth. A coin is actually 5.00 in. from an observer’s eye just above the surface, but it appears to be only 4.25 in. The real light ray from the coin makes an angle with the surface that is 8.1° greater than the angle the apparent ray makes. How much deeper is the coin than it appears to be? See Fig. 9.77.
