(d) It is a lens that forms real images for Do f.arrow_forwardSuppose you want to use a converging lens to project the image of two trees onto a screen. As show n in Figure CQ36.9, one tree is a distance x from the lens and the other is at 2x. You adjust the screen so that the near tree is in locus. It you now want the far tree to be in focus, do you move the screen toward or away from the lens?arrow_forwardA camera lens used for taking close-up photographs has a focal length of 22.0 mm.
