A tuba may be treated like a tube closed at one end. If a tuba has a fundamental frequency of 90.9 Hz, determine the first three overtones. Use 343 m/s as the speed of sound in air.
first overtone | How is the length of a tube closed at one end related to the resonant wavelengths that can be established in the tube? How are the frequency, wavelength, and speed of sound related? How are the harmonics related to the fundamental? Hz |
second overtone | How are the harmonics related to the fundamental? Hz |
third overtone | How are the harmonics related to the fundamental? Hz |

A tuba may be treated like a tube closed at one end. If a tuba has a fundamental frequency of 39.9 Hz, determine the first three overtones. Use 343 m/s as the speed of sound in air. Also, sketch a representation of the overtone described in parts a, b, and c. first overtone: Hz second overtone : Hz third overtone: Hz
If a wind instrument, such as a tuba, has a fundamental frequency of 54.0 Hz, what are its first three overtones (in Hz)? It is closed at one end. (The overtones of a real tuba are more complex than this example, because it is a tapered tube.) first overtone _________Hz second overtone _________Hz third overtone ____________Hz
4) A tube with one open end and one closed end has á resonant frequency of 71.0 Hz. Find the length of the tube- and find the first three overtones. Use 343 m/s for the speed of sound.
A tube, open at the left end and closed at the right, has standing-wave patterns at frequencies of 198 Hz and 330 Hz. The speed of sound in air is 343 m/s. The lowest two harmonics (normal modes) that these two standing waves could be are m = and The frequency of the fundamental (m = 1) is Hz. The wavelength of the fundamental mode is m. The tube is m long
If a wind instrument, such as a tuba, has a fundamental frequency of 37.5 Hz, what is its fifth overtone? It is closed at one end and the speed of sound is 330 m/s.
5) One of the harmonics of a column of air in a tube has a frequency of 576 Hz, and the next higher harmonic has a frequency of 704 Hz. What kind of tube is it - namely, is it open at both ends or open at one end and closed at the other end? How long is the tube? The speed of sound in air is 343 m/s. (SHOW YOUR WORK)
A 146-cm-long pipe is stopped at one end. Near the open end, there is a loudspeaker that is driven by an audio oscillator whose frequency can be varied from 10.0 to 4700 Hz. (Take the speed of sound to be 343 m/s.) (a) What is the lowest frequency of the oscillator that will produce resonance within the tube? Hz (b) What is the highest frequency that will produce resonance? Hz (c) How many different frequencies of the oscillator will produce...
A tube with a cap on one end, but open at the other end, has a fundamental frequency of 132.7 Hz. The speed of sound is 343 m/s. (a) If the cap is removed, what is the new fundamental frequency of the tube? (b) How long is the tube?
Question 1 Atube with one end open and one end closed creates two consecutive harmonic frequencies at 300 Hz and 330 Hz. If the speed of sound in air is 343 m/s, answer the following questions. a. What is the fundamental frequency of the tube? b. What is the length of the tube? c. If mith frequency is 300 Hz, find 91. 5+5+5
5. A person hums into the top of a well and hears that standing waves are established at frequencies of 42, 70, and 98 Hz. She happens to have a tuning fork with her. The 42 Hz frequency sound is not the fundamental (n 1) frequency. How deep is the well? Va 343 m/s. Hint: Overtones are the n > 1 multiples of the fundamental frequency. Determine the n 1 frequency of the well whch results in the given overtones....
