| Question | Answer |
| Waves | A disturbance from equilibrium that travels or propagates from one region of space to another. |
| Simple Harmonic Motion | Restoring Force and Acceleration is directly proportional to displacement from equilibrium x |
| Sinusoidal | Small amplitude vibrations |
| Period | Time taken for one cycle (T) |
| Frequency | Number of cycles per unit time (f) |
| Angular frequency | w=2*pi*f |
| Amplitude | Maximum displacement from equilibrium |
| Expression for Displacement as a function of time | x=ACos(wt) |
| A body that undergoes simple harmonic motion | A harmonic oscillator |
| Period for body undergoing SHM | T=(2*pi)/sqrt(m/k) |
| Expression for wavenumber | k=(2pi)/(lambda) |
