Answer to Question #106754 in Physics for Christian

Question

Suppose you changed both the length and the tension of a string at the same time. What would happen to the sound?

Answer 1

$$f=\frac{1}{2L}\sqrt{\frac{T}{\mu}}$$

If

$$\frac{L'}{L}=\frac{T'^2}{T^2}$$

then nothing changes.

In other case the frequency of sound changes.
