A tuba may be treated like a tube closed at one end. If a tuba has a fundamental frequency of 45.4 Hz, determine the first three overtones. Use 343 m/s as the speed of sound in air. first overtone second overtone third 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 How are the harmonics related to the fundamental? Hz How are the harmonics related to the fundamental? Hz
