Measure rotational speed
Rotational frequency (also known as rotational speed or rate of rotation) of an object rotating around an axis is the frequency of rotation of the object. Its unit is revolution per minute (rpm), cycle per second (cps), etc. The symbol for rotational frequency is (the Greek lowercase letter nu). Tangential speed v, rotational frequency , and radial distance r, are related by the following equatio… Web2. There is no light irradiated by the stroboscope. The object is rotating at a speed of 3,000 r/min, and the line cannot be seen by the naked eye. 3. If we gradually reduce the strobe frequency from 16,000 r/min, we will see five lines at 15,000 r/min. This means the stroboscope is emitting light five times for each rotation of the object.
