A strobe is a device that emits muzzle with adjustable frequency. It is the device that is often used in nightclubs to watch people dance in different fixed positions. Its performance is comparable to the electronic flash. Muzzle of a regular Cadence with a simple procedure can be obtained. The frequency of the muzzle is each hole takes a period, being the period of its circular motion. The STROBE is a tool invented by the mathematician and inventor Austrian Simon von Stampfer to 1829 which displays an object that is spinning as if was stationary or rotating very slowly. This principle is used for the study of objects in rotation or vibration, such as parts of machines and vibrating strings. It was developed at the same time that the Belgian physicist Joseph Plateau acknowledged the phenakistoscope.A strobe light regulated in the appropriate period may appear to freeze cyclical motion.
