(III) In a film projector, the film acts as the object whose image is projected on a screen (Fig. 23–59). If a 105-mm- focal-length lens is to project an image on a screen 25.5 m away, how far from the lens should the film be? If the film is 24 mm wide, how wide will the picture be on the screen? Film Lens Screen FIGURE 23-59 Film projector, Problem 57.
