Movie Projectors By: Ethan Que
A movie projector works when light shines through the thin strip of film, which is made out of celluloid A shutter is used to block the light while the film advances each frame, which ensures a smooth image. When you shine a light through them, the image is projected onto a wall and, by using lenses to magnify the image, can appear many times larger than the film itself. the light is then maginfied by the front lens and it creates a big image on the big screens.
