Concept explainers
Video projector An LCD video projector (LCD stands for liquid-crystal display) produces real, inverted, enlarged images of a small LCD picture on a screen (the display picture is upside down in the projector). If the display is located 12.6 cm from the 12.0-cm focal length lens of the projector, what are (a) the distance between the screen and the lens and (b) the height of the image of a person on the screen who is 2.0 cm tall on the display?
