Question 1.
Define what a node is in the context of standing waves.
Show hintHide hint
Think about where the wave is stationary.
Question 2.
What is the difference between an open-open pipe and an open-closed pipe?
Show hintHide hint
Focus on how sound can exit the pipe.
3Question 3.
What is the frequency of the first harmonic in an open-open pipe of length 2 m if the speed of sound is 340 m/s?
- 85 Hz
- 170 Hz
- 340 Hz
Show hintHide hint
Consider the formula for the fundamental frequency.
4Question 4.
True or False: An open-closed pipe can produce even harmonics.
- True
- False
Show hintHide hint
Recall the restrictions at the closed end.
Question 5.
A pipe that is closed at one end resonates at a fundamental frequency of 500 Hz. If the length of the pipe is 1.4 m, what is the speed of sound calculated from this information?
Show hintHide hint
Make sure to rearrange the formula for speed first.
Question 6.
Find the third harmonic frequency for an open-open pipe of length 0.75 m with a speed of sound of 340 m/s.
