What is the name of the device that housed images on long interchangeable strips that spin to create the illusion of motion?

• A. Slide Projector
• B. Magic Lantern
• C. Zoetrope
• D. Flip Book

Answer: (C)

The device that housed images on long interchangeable strips that spin to create the illusion of motion is known as a zoetrope. This invention dates back to the 19th century and operates on the principle of persistence of vision, which is the optical illusion that occurs when multiple images are shown in quick succession, leading the viewer to perceive smooth motion. In a zoetrope, a series of illustrations is affixed to a rotating drum or cylinder. As the cylinder spins and slits in the sides come into view, they reveal only one image at a time to the viewer. This quick succession of images creates the perception of animated movement as the viewer looks through the slits. The other options do not embody the same functional characteristics. A slide projector displays still images on a screen, while a magic lantern is an early type of projector that uses images on glass slides. A flip book, while it does create the illusion of motion, uses a different method—flipping through sequential images on pages rather than a rotating strip of images.
