Problem 18.14: A standing wave in a half-open pipe

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

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

  1. In which harmonic, n, does the air in the pipe oscillate?
  2. Determine the frequency fn of the tone produced by the pipe in this situation.
  3. Determine the fundamental frequency f1 (the lowest frequency of resonance in the pipe).
  4. Determine the speed of sound v.
