PURPOSE: Demonstrate stroboscopic effects.

DESCRIPTION: Several stroboscopic discs are available with a high-speed rotator and stroboscope. Look them over to find what interests you. Some are similar to the patterns seen on the obsolete stroboscopic piano tuners. Some are motional things like a swinging pendulum, shown in the photograph above. Another is actually the demonstration O2-21: STROBOSCOPIC CENCO, a shameless advertising ploy.

SUGGESTIONS:

REFERENCES: (PIRA unknown.)

EQUIPMENT: Stroboscope, stroboscopic discs with fast rotator.

SETUP TIME: None.
