    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 [itex]\lambda[/itex] 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.
