Hi,
i'm stuck with this question, i'm prob missing something easy.

the "c" above middle c on the piano has a frequency of 512 Hz. calculate the wavelength.

All you're given is the wavelength of a wave in air. So, even though you may have forgotten, there should be some relation between the wavelength and the frequency of a wave.
Is any relation between f and $\lambda$ coming to mind?

Here's another hint: you'll probably need to look up the speed of sound somewhere in your textbook, if the exercise doesn't give it to you already.
