I've got a rather strange question here. I need to find the length of an open tube (silver flute), but I have only been given the frequency of the note that it is playing and the outside temperate (as well as the thermal expansion coefficient for silver).
The only equations I know for frequency are $v = \lambda f$, $f = 1/T$, and $f = \omega/2\pi$. I'm not exactly sure, which equation to use.
I don't think the current temperature will help get this answer, but it looks like I will need it for a later question which gives a new temperature and asks for the new frequency. (I can handle this part with a simple Linear thermal expansion equation).
If anyone can point me in the right direction that would be fantastic, thanks.
