Lab #26.1 Sound: Slow Motion Wobbler

Purpose
In this activity, students will observe and explore the oscillation of a tuning fork.

Discussion
The tines of a tuning fork oscillate at a very precise frequency. That's why musicians use them to tune instruments. In this activity, you will investigate their motion with a special illumination system— a stroboscope.

Required Equipment
Low-frequency tuning forks (lower frequency forks work best for large amplitudes), bright strobe light with a widely variable frequency.
