Question

Are there any relationships you can find between these frequencies?

The major frequencies (at the peaks of this sound wave) are 330 Hz, 670 Hz, and 950 Hz.

Answer 1

Answer #1

the first graph shows time domain signal that is the amplitude of the signal vs time.

The second graph shows the spectrum of the signal, that is the magnitude of the signal vs frequency.

the question asked is, is there any relationship between the frequencies.

By analyzing the spectrum of the signal we can see that, the major frequencies (at the peaks of this sound wave) are 330 Hz, 670 Hz, and 950 Hz.

These frequencies are harmonics of the fundamental frequency, 330 Hz.

330*2 =660 Hz

330*3=990 Hz

Consider a musical instrument that can be regarded as a long pipe with both ends closed (see Fig. 1). Let the pipe length L=0.250 m. Closed ends mean that you should have nodes at the two ends. Assume sound speed to be v=330 m/s. (6 points) Consider a musical instrument that can be regarded as a long pipe with both ends closed (see Fig. 1). Let the pipe length L 0.250 m.

An old mining tunnel disappears into a hillside. You would like to know how long the tunnel is, but it's too dangerous to go inside. Recalling your recent physics class, you decide to try setting up standing-wave resonances inside the tunnel. Using your subsonic amplifier and loudspeaker, you find resonances at 5.0 Hz and 6.4 Hz , and at no frequencies between these. It's rather chilly inside the tunnel, so you estimate the sound speed to be 334 m/s ....
