Unformatted text preview: , where v = 343 m/s is the speed of sound in air (Example Q1.1, p. 16). If the fundamental mode (n = 1) has a frequency of f 1 = 440 Hz, then the length of the pipe is calculated to be L = 0.38977 m. Since the harmonic frequencies in this case are directly proportional to the fundamental frequency (f n = n f 1 ), the frequencies of its first three harmonics (n = 2, 3, 4) are f 2 = 2 (440 Hz) = 880 Hz f 3 = 3 (440 Hz) = 1320 Hz f 4 = 4 (440 Hz) = 1760 Hz . f n = n v 2L...
