A piano tuner stretches a steel piano wire with a tension of 765 N. The steel wire has a length of 0.800 m and a mass of 6.00 g.
1. What is the frequency f1 of the string's fundamental mode of vibration? (Express your answer numerically in hertz using three significant figures.)
=______ Hz
2.What is the number n of the highest harmonic that could be heard by a person who is capable of hearing frequencies up to f = 16 kHz?
n=_________________
v=frequency*wavelength
for fundamental frequency (first harmonic): wavelength=2L
v=(TL/m)1/2
(765*.8/.006)1/2=f*2*.8
f=200 Hz
