Question

An open organ pipe (i.e., a pipe open at both ends) of length L has a fundamental frequency f. If the organ pipe is cut in half, what is the new fundamental frequency?

Answer 1

If the organ pipe is cut in half, what is the new fundamental frequency? Hint A.1 Fundamental wavelength in an open pipe For a wave in an open pipe, the fundamental wavelength is the longest wave that "fits' in the pipe, with an antinode (point of maximum wave amplitude) at both open ends. Hin Fundamental frequency A.2 0, For speed of sound , wavelength , and frequency so the frequency of a wave is given by Thus, the fundamental frequency and the fundamental wavelength are inversely proportional.
