Consider a projector mounted on the ceiling in a classroom. There is a small display – a video screen inside the p unit. A lens is used to project an image onto the wall of the classroom. (a) Suppose the projector uses a converging lens with a focal length of 105 mm to create the image on the wa display is located 108 mm from the lens, what must the distance between the wall and the lens be in order the projected image? (b) If the display is 24 mm by 36 mm, what are the dimensions of its image on the wall? (c) Draw an accurate ray diagram of the slide, projector, and screen. Your diagram should clearly indicate the its image on the wall, the location of the lens, and the focal points of the lens.

(a) Suppose the projector uses a converging lens with a focal length of 105 mm to create the image on the wall. If the
display is located 108 mm from the lens, what must the distance between the wall and the lens be in order to focus
the projected image?
(b) If the display is 24 mm by 36 mm, what are the dimensions of its image on the wall?
(c) Draw an accurate ray diagram of the slide, projector, and screen. Your diagram should clearly indicate the display,
