1. Explain in detail how you found the object and image distances from the position data you recorded.
2. Draw careful, neat ray diagrams for a converging mirror and for a converging lens each with the object distance larger than the focal length.
3. Write at least one paragraph in which you define focal length, object and image distance and magnification. Explain the difference between real and virtual images. Include a discussion of the sign convention
4. Start with the thin lens equation and solve for the image distance in terms of the focal length and object distance. Use this to explain why you can expect a real image only when the object distance is greater than the focal length.
5. Look up the definition of diopter and use it to calculate the power of the converging lens you used in this experiment. What kind of visual problems can be helped with converging lenses?
