Across
  1. 4. The maximum height of a wave-measured from the centre line to the peak.
  2. 8. A wave where the vibrations causing the wave are parallel to the direction of energy transfer.
  3. 9. Number of waves produced (or passing a point ) in one second
  4. 11. A wave where the vibrations causing the wave are at 90⁰ (right angles) to the direction of energy transfer.
  5. 12. How far a point is from its rest position.
  6. 13. the time to produce one wave or for one wave to pass a point.
Down
  1. 1. A periodic disturbance (vibration) that transfers energy from the source to the surroundings.
  2. 2. A substance through which a wave travels, e.g. air, water, string.
  3. 3. Position on longitudinal waves where the particles are squashed closest together – highest pressure on sound wave.
  4. 5. Point of maximum displacement, at the top of a transverse wave.
  5. 6. Point of maximum displacement at the bottom of a transverse wave
  6. 7. the distance between a point on a wave and the same point on the next wave.
  7. 10. Place on longitudinal waves where the particles are most spread out (lowest pressure on sound wave).
