Using the thin lens equation and the magnification factor, show that for a spherical diverging lens, the image of a real object is always virtual, upright, and reduced.
Answer to relevant QuestionsA simple single-lens camera (convex lens) is used to photograph a man 1.7 m tall who is standing 4.0 m from the camera. If the man’s image fills the height of a frame of film (35 mm), what is the focal length of the lens? Using Fig. 23.28, derive (a) The thin lens equation and (b) The magnification equation for a thin lens. The geometry of a compound microscope, which consists of two converging lenses, is shown in Fig. 23.29. (More detail on microscopes is given in Chapter 25.) The objective lens and the eyepiece lens have focal lengths of 2.8 ...An optometrist prescribes a corrective lens with a power of +1.5 D. The lens maker starts with a glass blank that has an index of refraction of 1.6 and a convex front surface whose radius of curvature is 20 cm. To what ...A woman 1.7 m tall stands 3.0 m in front of a plane mirror. (a) What is the minimum height the mirror must be to allow the woman to view her complete image from head to foot? Assume that her eyes are 10 cm below the top of ...
