The Sound Of Music

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.

Seems right to me.
