- 2. Distance between a point on one wave and the same point on the next wave.
- 4. Region of a sound wave where the particles of the medium through which it is travelling have been pushed close together
- 6. The reduction of a medium's density
- 7. Number of waves produced by a source each second
Down
- 1. Waves that have the same direction of vibration as their direction of travel,
- 3. Maximum disturbance from its undisturbed position
- 5. Wave that consists of oscillations occurring perpendicular (or right angled) to the direction of energy transfer
