A stretched rubber band has a length of 0.10m and a fundamental frequency of 440Hz. What is the speed at which waves travel on the rubber band?

I need some ideas to do this problem. Thanks!

  • physics! -

    A half wavelength is .1 m long
    A wavelength is therefore .2 meters long
    distance = rate * time
    the wave goes a wavelength in a period
    The period is one over the frequency.

  • physics! -

    You know the wave equation, f*lambda=v

    lambda is twice the length of the rubber band.
