Homework Help: Water Waves - Universal Wave Equation

  1. Mar 30, 2010 #1
    Water Waves -- Universal Wave Equation

    1. The problem statement, all variables and given/known data

    Attached.

    2. Relevant equations

    v=fλ

    3. The attempt at a solution

    f= cycles/time
    f= 45/60
    f= 0.75 Hz

    The trouble I am having is wondering if λ is 28 m or do i have to do something else to find λ?

    No, the wavelength itself is not 28, but 28 is a factor of wavelength. One wavelength is the distance from crest to crest, or trough to trough, or however you want to see it. It is however long the wave is until it repeats itself.
