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.
