Definition
Noun: A strobe light is a scientific instrument that produces very short, intense flashes of light at precise, regular intervals. Its primary function is to make a rapidly moving or vibrating object appear stationary or to move in slow motion when viewed under its light, by synchronizing the flashes with the object's periodic movement.
Usage
A strobe light is used to study, measure, or observe high-speed periodic motion. * The technician used a strobe light to check the speed and alignment of the rotating fan blades. * In the physics lab, we observed a vibrating string under a strobe light to measure its frequency.
