The Sound Of Music

  1. Apr 19, 2009 #1
    1. A flute acts like an open pipe and sounds a note with a 370 - Hz pitch. What are the frequencies of the second, third, and fourth harmonics of this pitch?



    2. f = nv/2L (n = 1, 2, 3, 4)



    3. f = nv/2L
    370 = 343/2L
    740 L = 343
    L = 0.463513513

    f = 2(343)/ 2(0.463513513)
    = 740 Hz

    f = 3(343)/ 2(0.463513513)
    = 1110 Hz

    f = 4(343)/ 2(0.463513513)
    = 1480 Hz

    740 Hz, 1110 Hz, 1480 Hz ---- I'm not sure if this is right.
