SuggestedUses
•WaveDemonstrators
Use the Mechanical Wave Driver to drive a wave
demonstrator, such as PASCO's Model SE-9600 or
SE-9604, at any desired frequency and amplitude.
• Waves in a wire or string
Use it to produce waves in a stretched wire or string,
as shown below. You can determine resonance fre-
quencies as a function of length, or you can examine
the relationship between wave velocity and the tension
and mass per unit length of the string or wire.
• DrivenHarmonicMotion
Use it to drive a mass on a spring and compare the am-
plitude of the oscillations with drive frequency. To at-
tach a spring to the Wave Driver, remove the plastic
cover to the banana plug connector by unscrewing it.
There will be a hole through the connector to attach
the end of the spring. Resonant modes of coupled os-
cillators can be investigated using air track gliders
coupled by springs.
• ChladniPlates
Use it to vibrate sheets of metal or plastic, and observe
the standing wave patterns that are formed at resonant
frequencies. The patterns are easily seen by sprinkling
sand onto the surface of the metal or plastic sheet.
• RippleTanks
Use the Mechanical Wave Driver as the wave source
in a ripple tank. You'll have full control of the wave-
length.
• MolecularMotion
Use the Mechanical Wave Driver with a Molecular
Motion Model, such as PASCO Model SF-8563, to
demonstrate the kinetic theory of gases.
