1. The problem statement, all variables and given/known data A flute is essentially a pipe open at both ends. The length of a flute is approximately 66.3 cm. The speed of sound in the flute is 342 m/s. What is the first harmonic of a flute when all keys are closed, making the vibrating air column approximately equal to the length of the flute? Answer in units of Hz. What is the second harmonic? Answer in units of Hz. What is the third harmonic? Answer in units of Hz. 2. Relevant equations I found the equation for fundamental frequency in an open-ended tube online: f=v/2L. 3. The attempt at a solution f=v/2L f=342/2x.633 f=270.142 However, my assignment says this is wrong. I searched some more and found that harmonics are multiples of the fundamental frequency (f, 2f, 3f, etc.). I'm sure this is relevant, I'm just not sure how - finding 2f gave me an incorrect answer as well.
