Unformatted text preview: Problem 3 A lens produces a real image that is twice as large as the object and located 15 cm from the lens. What kind of lens is this? What is the focal length of e ns? hat e bject istance? the lens? What is the object distance? Problem 4 A lens has a focal length of 32 cm. What kind of lens is this? Find the image distance and magnification that results when an object is placed 23 cm in ont f is ns front of this lens. Problem 5 Given the compound lens system below, use a ray diagram to find the approximate location of the image. Then use the thin lens equation and find the istance om e cond ns e nal age distance from the second lens to the final image....
