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.
