Survey of Motion Pictures Exam 1 Practice

Two pictures printed on opposite sides of a small disk are seen as one image when the disk is spun fast, thanks to persistence of vision. That spinning toy is called a thaumatrope. It’s a simple early device that demonstrates how two separate images can fuse into a single illusion when viewed in quick succession, which is a foundational idea behind animation and motion pictures. The other options are projection or capture devices, not spinning toys that blend two pictures: a magic lantern shows projected slides, a camera obscura projects reality through a small aperture, and photography is about capturing images with a camera.
