When you have a wave in sound inside a piston of length L, A.P. French says that the fundamenal frequency \nu of an oscillation is given by
\nu = 1/4L \sqrt{(\gamma p / \rho)}
Where p is the pressure, \gamma is the factor that accounts for adiabatic compression of the gas, and \rho is it's density.
My question is this : doesn't the pressure p vary as you compress the gas? How can you assume it to be constant?
