Standing Sound Waves Video Lessons

Concept

Problem: The frequency of the standing wave shown in the figure(Figure 1) is 175 Hz. What is the fundamental frequency of this pipe? What is the length of the pipe?

FREE Expert Solution

The nth harmonic is given by:

$\overline{){{\mathbf{f}}}_{{\mathbf{n}}}{\mathbf{=}}{{\mathbf{nf}}}_{{\mathbf{1}}}}$, where n is an integer and f1 is the fundamental frequency.

The pipe is open on both sides.

The first harmonic is then A - N - A

The second harmonic A - N - A - N - A = 175 Hz
