Many objects in the physics classroom move or vibrate much more rapidly than the human eye can detect. One way to observe these objects is to use our Economy Digital Strobe. It features nine flashing LEDs that can be tuned from 1 to 255 Hz with +/- 2% accuracy. It is also designed for basic use and is great for measuring the frequency of a vibrating string.
