Stroboscopic Effect
The stroboscopic effect occurs when a flashing strobe light periodically lights up an object. The motion of the object between flashes is invisible, and the object is only visible when the light flashes.
This effect also shows up when recording. If a camera is recording at 30 frames per second (fps), it takes 30 pictures per second. If the movement in the scene occurs at the same frequency, or an exact multiple of the frequency, there will be no movement visible.
