Amplitude
Amplitude is the maximum displacement of a vibrating particle from its equilibrium position.
It shows how large the oscillation is.
For a transverse wave, amplitude is often measured from the equilibrium line to a crest or trough.
Energy and Amplitude
For many waves, greater amplitude means greater energy transfer.
In simple wave systems, energy is often related to the square of amplitude:
Energy ∝ A²

Common Mistakes
- Mistake
Amplitude is not crest-to-trough distance.
- Mistake
Crest-to-trough distance is approximately 2A.
- Mistake
Amplitude is not wavelength.
