"Second harmonic is the length of the string"
A string is 0.1 meter long. The speed of the string is 100 m/s. What's the frequency of the first harmonic?
0.1=(2)W/2 so W=0.1 m, then 100m/s= f*0.1, so f= 1000 Hz
But my book states that my answer is wrong. It states that the answer is 500 Hz.
That means it ignored the rule quoted above!
0.1=(1)W/2 so W=0.2 m, then 100m/s= f*0.2, so f= 500 Hz
I'm looking for the TRUTH!!! Please enlighten me.
