Req Pratical 8: Ripple Tank

• What is the purpose of a ripple tank?

  To observe the features of water waves
• What equipment is used in a ripple tank?

  A shallow tray of water and a vibrating bar
• How do you visualize waves in a ripple tank?

  By shining light through the water onto paper
• How can you measure the wavelength of water waves?

  By measuring the distance of 10 wavelengths
• How is frequency defined in the context of waves?

  As the number of waves passing a point each second
• How can you accurately measure frequency?

  By counting waves in 10 seconds and dividing by 10
• What is the wave speed equation?

  Wave speed = frequency × wavelength
• What is another method to determine wave speed?

  Measuring the time for a wave to travel the tank
• Why might results differ using two methods to measure wave speed?

  Due to measurement errors
