Chapter 23 Mirrors and Lenses Quick Quizzes 1. At C . ± ² ± ± ² ³ ´ µ ± 2. (c). Since n , the virtual image of the fish formed by refraction at the flat water surface is closer to the surface than is the fish. See Equation 23.9. water air n > 3. (a) False. A concave mirror forms an inverted image when the object distance is greater than the focal length. (b) False. The magnitude of the magnification produced by a concave mirror is greater than 1 if the object distance is less than the radius of curvature. ( c) True. 4. (b). In this case, the index of refraction of the lens material is less than that of the surrounding medium. Under these conditions, a biconvex lens will be divergent.
