    • What equipment is used in a ripple tank?
      A shallow tray of water and a vibrating bar
    • How is the vibrating bar powered in a ripple tank?
      It is connected to a power pack
    • What are the steps to measure the wavelength of water waves in a ripple tank?
      1. Place a ruler on the paper.
      2. Freeze the image of the waves.
      3. Measure the distance of 10 wavelengths.
      4. Divide by 10 to find one wavelength.
    • How is frequency defined in the context of water waves?
      Number of waves passing a point each second
    • What is the method to find frequency more accurately?
      Count waves in 10 seconds, then divide by 10
    • What is the wave speed equation?
      • Wave speed = frequency × wavelength
      • Frequency in Hertz
      • Wavelength in meters
    • Why might results differ between methods of measuring wave speed?
      Due to measurement errors in time
