| Question | Answer |
| Transverse wave | a wave where the direction of the vibration is perpendicular to the direction its traveling |
| Longitudinal wave | a wave where the direction of the vibration is parallel to the direction it is traveling |
| Properties of a wave | 1. Reflection 2. Refraction 3. Interference 4. Diffraction 5. Polarisation |
| Define- 1. Reflection 2. Refraction | 1. The bouncing of waves off of an obstacle. 2. The changing of direction of a wave when it enters a region with a different speed. |
| Define- 3. Interference 4. Diffraction 5. Polarisation | 3. When the waves from 2 separate source s meet a new wave is formed. (constructive and destructive) 4. the sideways spreading of waves around an obstacle 5. reducing the wave to travel in one direction |
| The Doppler Effect | The apparent change in the frequency of waves due to the motion of the source or the observer (f ') |
