Table 1: One Lens (18 points) Object Distance Image Height h (ст) Image Distance Object Distance Image Distance Image Height h (cm) P (cm) P (cm) (cm) (ст) 1O. 2 20.2 24.5 .95 27.0 31. 2 34 2 35.8 17.50 100.00 10 3 10.4 15.00 80.00 7.91 9.17 10-75 14.00 70.00 1-07 13.00 50.00 I140 4.00 18.20 4.27 12.00 30.00 11.50 20.00 1) Using Excel, or some other graphing program (or by hand), make a graph of Image Distance vs. Object Distance (q vs. p), then answer the following question about this graph. (10 points) 2) What value does the image distance approach as the object distance becomes larger? (5 points) 3) What value does the object distance approach as the image distance becomes larger? (5 points) 4) How do the values of the answers to questions 1, and 2 relate to the lens used in part 1? (5 points) 5) What is the relationship between image distance and object distance? (Directly related or inversely related?) Give evidence supporting your answer. (5 points) 6) What is the relationship between object distance and image height? (Directly related or inversely related?) Give evidence supporting your answer. (5 points) Where would you place the object to obtain an image as far away from the lens as possible? (5 points) 7) 8) Where would you place the object to obtain an image located at the focal length of the lens (100 mm)? (5 points)

Answer 1

5) From the given table's first and second column it is apparent that as the object distance is decreasing, the image distance is increasing so the object distance and the image distance are inversely related to each other. 6) From the given table's first and third or fourth and sixth column it is apparent that as the object distance is decreasing, the image height is increasing so the object distance and the image height are inversely related to each other 7) To get the image as far away as possible (at infinity) we can place the object at the focal point of the lens 8) To get the image at the focal point of the lens we can place the object at infinity or practically speaking, put the object as far away as possible
