Waves type problem 1)

  1. Jan 20, 2012 #1
    1. The problem statement, all variables and given/known data
    There is a water wave having a speed of .25 meter per second that causes a cork to move up and down 4.0 times in 8 seconds
    what is the wavelength of the water wave

    2. Relevant equations
    v=f times wavelength
    T=1/f
    x=vt

    3. The attempt at a solution
    I used the formula wavelength =v/f and I plugged v for 0.25 m/s.
    For frequency I plugged 8 seconds but Idk think I did that part right. I'm alittle confused on what 4.0 times in 8 seconds is? Like is it the period?

    Do you understand what frequency is? (Hint** time is not frequency. What units does frequency have?)
