    Re: Wavelength

    Depends on the wave velocity, right?

    You should be able to find the equation that relates Frequency, Wavelength and Velocity.

    Or, you can just figure it out by their units:

    Frequency is in 1/seconds, or Hz

    Wavelength is in meters

    Velocity is in meters/seconds

    Since the units have to be the same on both sides of an equation, what do you think you divide by what to get what?
