a 32 cm violin string with linear mass density is .36 gm/m is placed near a loudspeaker that is fed by an audio oscillator of variable frequency. It is found that hte string is set into oscillations at frequencies 1320 Hz and 1760 Hz as the frequency of the audio oscillator is varied continuously over the range of 1000-1800 Hz. Which harmonic is the 1320 Hz for the violin?
L = (wavelength)/2
v = (frequency)*(wavelength)
The Attempt at a Solution
I am attempting to find the "lowest frequency of oscillation". so f=v/(2*L). L is known, but v is not. I am trying to find the velocity of the string, but this is where I encounter a problem.
