Apparatus:
function
generator,
mechanical
oscillator,
resonance
strips
Description:
As
the
oscillator
is
quite
delicate,
carefully
attach
the
resonance
strips
and
unlock
the
piston.
Fan
the
strips
evenly
over
360°
and
sweep
through
frequencies
with
the
function
generator.
Each
strip
is
of
the
same
material,
but
of
differing
lengths
such
that
each
strip
has
a
unique
resonant
frequency.
