Finding Wavelength

  1. Feb 25, 2008 #1
    Hey, I'm stuck on how to find the wavelength of a question I have got given for homework.

    The question shows a tray of water with waves and the length of the tray is 10cm. It says... The diagram shows some waves in a ripple tank travelling at a sppeed of 6cm/s. What is a) the wavelength b) the frequency

    Can anyone help?? xx

    count the number of "hills" and "valleys", one wavelenght is one "hilL" + one "valley".

    Then divide by the lenght of the tray.
