What is the wavelength of the fundamental resonant frequency of a closed tube that is 35 cm long?

Answer

A resonance tube is a device that is used to determine the velocity of sound in air by measuring the resonant frequencies. The wavelength of the fundamental resonant frequency of a closed tube 35cm long depends also on the diameter of the tube. The formula used is L + d/4 = n?/4, with l as the length, d as the diameter, n as the harmonic used and ? the wavelength.

The length of the tube is going to be proportional to the resonant wavelengths, hence it will be inversely proportional to the frequencies.
