Across
  1. 3. The highest point above the plane of vibration in the direction that the wave is moving.
  2. 5. the material through which a wave travels
  3. 7. The distance between two corresponding parts of a wave.
  4. 8. The unit of frequency, measured in number of waves per second.
  5. 10. Those waves that vibrate at right angles to the direction that the wave is moving.
  6. 12. The maximum distance that matter particles in a crest or trough is from the particles' rest position.
  7. 13. The bending of waves as they move around a barrier or through an opening.
  8. 14. The number of waves that pass a given point in certain amount of time.
Down
  1. 1. those waves that require a medium to be present in order for the waves to move.
  2. 2. The interaction between waves when they meet.
  3. 3. The point in a longitudinal wave where the matter particles of the medium are closest together.
  4. 4. The bending of a wave as the wave passes from one medium to another medium.
  5. 6. The bouncing back of a wave when the wave hits a surface through which the wave cannot pass.
  6. 9. The lowest point below the plane of vibration in the direction that the wave is moving.
  7. 11. the ability to do work or cause change.
