1. The problem statement, all variables and given/known data
Question: Standing Waves:
A steel wire in a piano has a length of 0.7000m and a mass of 4.300 x 10^-3 kg. To what tension must this wire be stretched in order that the fundamental vibration correspond to middle C (fc=261.6 Hz on the chromatic musical scale)?
2. Relevant equations
f1=v/wave1 = v/2L
3. The attempt at a solution
v=2Lf1= (.7000m)(261.6Hz)= 183.12 m/s
