 Mentor P: 41,325 Calculating Overtones 147 Hz is the frequency, not the wavelength! Use the wave equation ($v = f \lambda$) to find the wavelength, if you want to. But you don't need to find the wavelength or the length of the tube to solve this problem. What I want you to understand is the relationship between the wavelength of the fundamental frequency and the wavelength of the first harmonic. (If you know how the wavelengths relate, then you should be able to figure out how the frequencies relate via that wave equation.) Draw yourself a picture of the open/closed tube and draw the fundamental wave.
