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

f1=v/2L
v=2Lf1= (.7000m)(261.6Hz)= 183.12 m/s
