Question
Please answer all short answer questions!1. What value does the image distance approach as the object distance becomes larger?
2. What value does the object distance approach as the image distance becomes larger?
3. What is the relationship between image distance and object distance? (Directly related or inversely related?) Give evidence supporting your answer.
4. Where would you place the object to obtain an image as far away from the lens as possible?
5. Where would you place the object to obtain an image located at the focal length of the lens (100 mm)?
6. Using your answer from above and your experiences in this activity, explain why ”fixed lens” cameras require that the subject of the photo be a minimum distance from the lens.
Explanation / Answer
1 . the image goes to focal point , image distance = f = focal lenght 2 . again the focal length. 3.lens equation is 1/v + 1/u = 1/f .this is the relation between them. 4. at the focal point. 5.at infinity. 6.a minimum distance is required to focus the image . only when the object is at infinity then only the image can be projected at the focal point .
