Analysis
10. The graphs show inverse image distance (vertical axis) versus inverse object distance (horizontal axis). The graph also shows a curve fit for the data. Is image distance directly or inversely proportional to object distance? Write a description of the graphs. (2 points)
11. For the lens and the mirror, what are the slope and the y-intercept from the linear fit to your data? (2 points)
12. From the line fit, what is the focal length of each lens and mirror? Compare your measured value with the nominal value written on each by calculating a percent difference. (2 points)
Questions
13. What value does the image distance approach as the object distance becomes larger? (2 points)
14. What value does the object distance approach as the image distance becomes larger? (2 points)
15. Where would you place the object to obtain an image as far away from the lens as possible?
Where would you place the object to obtain an image located at the focal length of the lens (100 mm)? (2 points)
