Question

a flute is essentially a pipe open at both ends. the length of a flute is approximately 66.1 cm. what is the third harmonic of a flute when all keys are closed, making the vibrating air column approximately equal to the length of the flute?

If .661cm is a half wavelength, then lambda = 2*.661m, and third harmonic is 1/3 of that wavelength, or 2*.661/3=.440m

f= speedsound/wavelength= appx 343/.440=778hz check my work.
