Travelling Waves includes the following learning objectives:

  • Describe a wave pulse and a continuous progressive (travelling) wave;
  • State that progressive waves transfer energy;
  • Recall and use f = 1/T;
  • Derive and apply the relationship between wave speed, wavelength and frequency;
  • Measure the frequency of sound using a cathode ray oscilloscope;
  • Recall and use the relationship: Intensity ? Amplitude?;
  • Use the relationship: Intensity = Power / Cross-Sectional Area.
