Across
- 3. The number of waves per second
- 7. A transverse wave is one where the particles move at right angles (90°) to the direction of travel of the wave
- 8. A longitudinal wave is one where the particles vibrate along the same direction as the wave.
Down
- 1. The horizontal distance from one point on a wave to the same point on the next wave (e.g. crest to crest)
- 2. The top point of a wave
- 4. The bottom point of a wave
- 5. The time taken for one wave to pass a point
- 6. The vertical distance from the axis to the crest or to the trough
