3. Unlock the drive arm locking tab.
4. Plug the output from your function generator into the
banana plug receptacles on the front of the driver.
5. Adjust the frequency and amplitude of the function gener-
ator to produce mechanical waves with the frequency and
amplitude you want. The current should not exceed 1
ampere.
Suggested Uses
Wave Demonstrators Use the Mechanical Wave Driver
to drive a wave demonstrator such as the SE-9600 Transverse
Wave Demonstrator or the SE-9604 Longitudinal Wave Dem-
onstrator,
Wave on a Wire or String Use the driver to produce
waves in a stretched wire or string. Determine the resonant fre-
quencies as a function of length, or examine the relationship
between wave velocity and the tension and mass per unit
length of the string or wire.
Driven Harmonic Motion Drive a mass hanging on a
spring and compare the amplitude of the oscillations with the
drive frequency. Use the String Holder with Plug to attach the
spring to the drive arm. Resonant modes of coupled oscillators
can be studied using air track gliders or carts on a track coupled
by springs.
Chladni Plates Use the driver to vibrate sheets of metal
and observe the standing wave patterns that are formed at reso-
nant frequencies.
Resonant Loops and Strips Use the driver to vibrate a
resonant loop to show standing waves on a wire and vibrate
resonant strips to demonstrate standing waves, harmonics, and
the relationship between length, frequency, and resonance.
Molecular Motion Use the driver with the Molecular
Motion Model (SF-8563) to demonstrate the kinetic theory of
gases.
