Talk:Fundamental frequency
From Wikipedia, the free encyclopedia
Is it save to define fundemantal frequency using the term "pitch"? Typically I see the pitch defined in terms of perceived fundamental frequency. Is the circular definition avoidable?

[edit] Diagram

[edit] Velocity of a sound wave
From [1]: "The velocity of a sound wave at different temperatures:
* V = 343 m/s at 20 °C * V = 331 m/s at 0 °C"
Are we to assume that that's at standard atmospheric pressure? I think that the pressure should be quoted as well as the temperature since it's a relevant quantity.
Also, I would be inclined to use a lowercase v for velocity, but that's probably more of a matter of opinion than relevant physics. Stuart Morrow 18:17, 25 February 2007 (UTC)
The speed of sound is only dependent on the type of medium (or more specifically, the specific heat of it) and the temperature. The pressure doesn't affect the speed of sound unless it's great enough to change the matter itself (change of state or separating components). 164.107.197.169 20:13, 28 March 2007 (UTC)
I'm pretty sure it is dependent on pressure. But not all that much.128.95.209.67 (talk) 23:47, 7 February 2008 (UTC)
[edit] Expression for the string, and mass with spring
If the expression of an open tube and closed tube is in this article, should the expression for mass with a spring be included too? (w=sqrt(m/k) same for the string, that apears in the drawing. Trufetes 23:29, 2 December 2007 (UTC)
[edit] Derivations of Formulae
It would be quite helpful to include mathematical derivations of the formulae presented, along with an intuitive explanation of the derivations. This would help the reader understand WHY things like tubes, etc. resonate. Tpkaplan (talk) 04:08, 19 May 2008 (UTC)
