Problem 18.14

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 f_n 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.
