(Sorry I cannot follow the question format because this question is(adsbygoogle = window.adsbygoogle || []).push({}); relatedto a problem, but is not the problem itself.)

I am talking about the linear density μ that appears in this equation:

v = sqrt(T/μ)

.. used usually for musical instruments, whereμ = m/L

Now, I am wondering which value of L we use.

Say that you have a string that is normally .1 kg and .10 meters long.

Now lets say thatu stretch the string to .12 metersto make some musical instrument.

For L value, do we plug in .12 meters or .10 meters?

Thanks!
