PRACTICE IT Use the worked example above to help you solve this problem. A coin 2.49 cm in diameter is imbedded in a solid glass ball of radius r = 31.9 cm (see figure). The index of refraction of the ball is 1.50, and the coin is d = 21.3 cm from the surface. (a) Find the position of the image of the coin. cm (b) Find the height of the coin's image. cm EXERCISE HINTS: GETTING STARTED I I'M STUCK! A coin is embedded 21.3 cm from the surface of a similar ball of transparent substance having radius 31.9 cm and unknown composition. The coin's image is virtual and located 16.0 cm from the surface. (a) Find the index of refraction of the substance. n = (b) Find the magnification. M =
