Which device uses light to display an image from film?

• A. Projector
• B. Camera
• C. Printer
• D. Microfilm Reader

Answer: (A)

The main idea is how a device turns film frames into a visible image for an audience by using light. A projector does exactly that: it shines light through the film frames and uses a lens to project an enlarged image onto a screen, producing the moving pictures you see in a cinema or classroom. The other devices have different purposes— a camera captures light to record images, not to display them; a printer creates a physical copy on paper, not a projected screen; a microfilm reader uses light to magnify and view microfilm, which is for reading stored documents rather than showing cinematic images to an audience. So, the projector is the device that best fits "uses light to display an image from film."
