Open pipe frequency formula
WebOpen organ pipe is the one with two open ends, and instead of the formula you mention you need to use L = n v 2 f n where f n is the frequency of the n t h mode, and n = 1, 2, 3,... your formula is for a closed organ pipe (with one open and one closed end). EDIT WebThe resonant frequencies of an open-pipe resonator are. f n = n v 2 L, n = 1, 2, 3..., f n = n v 2 L, n = 1, 2, 3..., where f 1 is the fundamental, f 2 is the first overtone, f 3 is the second …
