The Wagon Wheel Effect | Optical Illusion Science Experiment

The video explains the wagon wheel effect, a visual illusion where rotating objects appear to move differently due to frame rate and speed. Using a clock, the video demonstrates how frame rates can make objects seem to move backward or freeze. Viewers can observe this effect with household items like fans and drills. For precise measurement, a tachometer can be used to measure rotational speed, converting RPM to revolutions per second. The video also provides tips on camera settings to reduce motion blur and enhance the effect.
