Which device is an early projector using painted glass slides?

• A. Magic Lantern
• B. Camera Obscura
• C. Photography
• D. Thaumatrope

Answer: (A)

An early projection device works by shining light through painted glass slides to cast an image onto a screen, which is exactly how a magic lantern operates. This device uses a light source behind glass slides that are hand-painted or printed, with a lens to magnify and project the image onto a wall or screen for an audience. It was a popular way to tell stories and present educational visuals well before motion pictures, and it laid important groundwork for later cinema by demonstrating projected imagery. Compared to the other options, the camera obscura is a passive projection of the outside world through a small opening, not based on slides or a prepared image. Photography focuses on capturing an image on light-sensitive material rather than projecting a prepared image onto a surface. The thaumatrope is a simple spinning toy that creates the illusion of motion from two images on opposite sides of a card, not a device for projecting painted slides.
