This animation takes 3 to 5 seconds to load.
Please wait for the animation to completely load.

The animation shows a standing wave in an open pipe (position is given in centimeters and time is given in seconds). Restart.

  1. In which harmonic, n, is the air in the pipe oscillating?
  2. Determine the frequency fn of the tone produced by the pipe in this situation.
  3. Determine the frequency of the eighth harmonic f8.
  4. Determine the speed of sound v.
