Across
- 2. waves oscillate along paths at right angles to the direction of the wave's advance
- 4. highest surface part of a wave
- 6. the area of a wave (or Slinky) that is spread out.
- 7. maximum distance
- 9. describes how long the wave is
Down
- 1. the number of waves that pass a given point in one second.
- 3. partie motion is in the same direction in which the wave is propagating.In longitudinall waves all particles in the material oscillate parallel to the propagation direction.
- 5. the lowest part of a wave
- 8. disturbance that transfers
