K, Q, F, and R AP B 1993 MC 69 002 10.0 points If the object distance for a converging thin lens is more than twice the focal length of the lens, the image is 1. virtual and erect. 2. located at a distance more than 2 f from the lens. 3. larger than the object. 4. located at a distance between f and 2 f from the lens. correct 5. located inside the focal point. Converging Lens 003 10.0 points The magnification produced by a converging lens is found to be 3 . 2 for an object placed 22 cm from the lens. What is the focal length of the lens? Correct answer: 32 cm. Converging Lens 04 004 10.0 points A converging lens of focal length 0 . 237 m forms a virtual image of an object. The image appears to be 0 . 854 m from the lens on the same side as the object. What is the distance between the object and the lens? Correct answer: 0 . 185516 m. Converging Lens 08 005 (part 1 of 2) 10.0 points An object is placed 1 . 2 m in front of a con- verging lens of focal length 24 cm. What is the distance to the image? Correct answer: 30 cm. 006 (part 2 of 2) 10.0 points What is the magnification of the object? Correct answer:- . 25. Convex Lens 02 007 10.0 points A convex lens is needed to produce an image located 50 cm behind the lens that is 0 . 68 the size of the object.
