What will change the velocity of a periodic wave?

OpenStudy (anonymous):

\[v=f \lambda\]Where v is the speed of ANY wave, f is the frequency of that same wave and lambda is the wavelength of that wave. When I say ANY, I mean that the formula applies to sound, light, or any other wave you can think of.
