Outcomes
- Pupils understand and can use the terms amplitude, frequency, wavelength and period.
- Pupils can describe the differences between longitudinal and transverse waves and give examples of each.
- Pupils recall that waves transfer energy without transferring matter.
- Pupils can use the wave equation <math>v=f \lambda</math>

- Introduce the concept of a wave by showing pupils examples of different types of wave in which the wave nature is obvious: water, seismic (P and S, not Love) and "Mexican".
Main Body of Lesson
- Use wave tank to demonstrate water waves. Ask pupils what aspect of the waves could be changed. Elicit "size" and "oftenness".
- Explain "size" of waves as amplitude and ask pupils what the effect of changing amplitude would be on sound waves (volume), seismic waves (more/less damage), "Mexican" (more/less movement - e.g. seated/standing), light (brightness).
- Explain "oftenness" as frequency.
