H1-12: VISIBLE WAVEFORMS ON LARGE SPEAKER

Additional Info

  • ID Code: H1-12
  • Purpose: Show the loudspeaker motion produced by waves of various shapes.
  • Description: Using waves of a few Hertz, the shape, amplitude and symmetry of the pulses can, to a limited extent, be observed by watching the movement of the speaker cone. The oscillator must have a reasonably large amplitude.

    This can be a good demonstration for student interactivity; ask them to predict how what they see will change with different wave shapes, frequencies, and amplitudes. A video camera can be provided upon request to make the demonstration more visible in large classrooms.
