A, C, and P 2. A, E, C, and G 3. A, P, and G 4. A, E, R, and G 5. C and R 6. E and P 7. A, E, and P 8. E and R 9. A, C, and R 10. A, R, and G 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 between f and 2 f from the lens. 3. located at a distance more than 2 f from the lens. 4. larger than the object. 5. located inside the focal point. 003 10.0 points The magnification produced by a converging lens is found to be 2 . 2 for an object placed 19 cm from the lens. What is the focal length of the lens? An- swer in units of cm. 004 (part 1 of 3) 10.0 points A diverging lens has a focal length of 19 . 7 cm....
