Experiment 2: The three harmonics you produced on the spring represent three way

Question

Experiment 2: The three harmonics you produced on the spring represent three ways in which a string on a musical instrument such as a guitar can vibrate. Which of the three harmonics on a guitar string would produce the sound with the highest pitch? 3:28 PM OO T-Mobile LTE 13% atlm.view.usg.edu 1 (16 points) What is the difference between the positions of the third and the first terms of wave length?

Explanation / Answer

1. Third option . 3/4 wavelength

2. No

3. In general, addition of loops to a spring decreases the restoring force therefore, the frequency of vibration will decrease. Third option is suitable. But if there is something more given in the experiment then nothing can be said without knowing the details of the experiment.

4. The one that vibrates the most.

5. Last option : 1 time higher and 2 times higher

6. Third option : six loops and six times higher.
