| Quantity | Symbol | Unit | Meaning |
|---|---|---|---|
| Wavelength | λ (lambda) | m | Distance between identical points on adjacent waves |
| Frequency | f | Hz | Number of waves passing a point per second |
| Period | T | s | Time for one complete wave (T = 1/f) |
| Amplitude | A | m | Maximum displacement from rest position |
| Wave speed | v | m/s | Speed at which wave travels |
The Wave Equation
v = f à λ
Wave speed (m/s) = frequency (Hz) Ă wavelength (m)
