The concept of multiple cameras triggered by trip wires is known as which?

• A. Muybridge Experiment
• B. Zoopraxiscope
• C. Kinetoscope
• D. Black Maria Rotation

Answer: (A)

This item tests understanding of how early motion studies captured movement with automatic triggers. Muybridge conducted famous experiments by lining up multiple cameras along a track and using trip wires to trigger each camera as the subject—often a horse—passed by. This setup produced a rapid sequence of photographs showing successive moments of a movement, laying the groundwork for studying motion in detail. The term most associated with this approach is the Muybridge experiments.

The other options refer to different parts of early motion picture technology: the Zoopraxiscope was a device for projecting sequences of still images to simulate motion, not a triggering method; the Kinetoscope was Edison’s single-viewer device for watching films; and the Black Maria was a studio built for filming.
