| Question | Answer |
| Waves | Transfers energy and information without transferring matter |
| Displacement | The position of a particular point on a wave, at a particular instant in time, measured form the mean (equilibrium) position (Symbol x, Units m) |
| Amplitude | Magnitude of the maximum displacement reached by an oscillation in the wave (Symbol A, Units m) |
| Frequency | The number of complete wave cycles per second OR the number of waves passing a point in one second (Symbol f, Units Hz) |
| Wavelength | Distance between a point on the wave and the same point on the next wave cycle (Symbol λ, Units m) |
| Period | Time taken for one complete oscillation at one point on the wave ALSO the time taken for the wave to travel one complete wavelength (Symbol T, Units m) |
| Phase | the part of the wave cycle that a given point is at. Measured in angle units as a cycle is seen as a full circle (360°, 2π rad) (Units rad) |
| Wave Speed | Rate of movement of the wave (Symbol v/c for EM, Units ms-1) |
