An LCD (liquid crystal display) projector works by illuminating a small LCD display-not unlike a small computer screen-with a very bright light and using a lens to form an image of the display on the viewing screen. A small LCD projector has a 5.00-cm-tall LCD display, and the lens needs to create a 1.60-m-tall image. The screen is 4.50 m from the LCD display
