Key Stage 3
Meaning
The amplitude of a wave is the distance between the peak of a wave and the midpoint of the wave.
About Amplitude
The greater the amplitude of:
 |
 |
 |
| This is a high amplitude wave. | This is a low amplitude wave. |
Key Stage 4
Meaning
The amplitude of a wave is the maximum displacement of the wave from its equilibrium position.
About Amplitude
The greater the amplitude of:
|
|
|
| This is a high amplitude wave shown by the large displacement between the peak (or trough) of the wave and the equilibrium position. | This is a low amplitude wave shown by the small displacement between the peak (or trough) of the wave and the equilibrium position. |
