Resonance physics

7. An 80.0 cm long closed tube is used in a pipe organ. Assume the speed of sound to be 343 m/s. a. Draw the wave representing the fundamental and first overtone if the pipe is i. closed at one end only. ii. open at both ends. fundamental first overtone fundamental first overtone (3'd harmonic) (2nd harmonic) b. Determine the frequency of the fundamental and first overtone if the pipe is i. closed at one end only. [107 Hz, 322 Hz] ii. open at both ends. [214 Hz, 429 Hz]
