Problem 4 Consider the imaging lens of focal length fas shown in Figure 3. An object is placed at distance d1 to the left of the lens and an image is observed on a screen at distance d2 to the right. A. What is the relation between d1, d2, and f? B. Is the image inverted with respect to the object or not? C. What is the magnification? D. We are told the lens has a circular aperture of diameter D. What is the f-number? Figure 3 E. (BONUS) We now add another lens of focal length f at distance d2+d3 from the lens of part (D), as shown in Figure 4. At what distance d4 from the second lens will the image appear? Is the image inverted? What is the magnification? ( d1 - d2 d3 d4 Figure 4
