With the classic sonometer, students can investigate waves on a wire by adjusting the wire tension and length and listening to the difference in tone when the wire is plucked or bowed. It is a useful demonstration, but it is only qualitative.

With the PASCO Sonometer and the Driver/Detector Coils, students can vary the density, tension and length of the wire, adjust the driving frequency and examine the resulting waveform in full detail on an oscilloscope or computer interface. This is all done quantitatively.

Features include a slotted tensioning lever, magnetic mounts, built-in scale and a sound box.

Experiments

Using a PASCO computer interface to monitor the detector signal makes it easier to measure and document the relationship between the wave amplitude and frequency. Use the Fast Fourier Transform (FFT) mode for a more sophisticated analysis of wave behavior on a string. The Sonometer's immediate audio feedback from the vibrating string with DataStudio's sophisticated analysis techniques adds reality to advanced concepts.

 

    In the Laboratory

    The included Sonometer Manual contains a discussion of the theory of waves on a stretched string, and student-ready experiments for investigating the resonant modes of a stretched string and for measuring the velocity of wave propagation on a string.
