Chapter 31, Problem 43P
LCD projectors commonly used for computer and video projection create an image on a small LCD display (see Application on page 369). The display is mounted before a lens and illuminated from behind. In a projector using a 7.50-cm-focal-length convex lens, where should the LCD display be located so the projected image is focused on a screen 6.30m from the lens?
