Across
  1. 1. The number of complete waves passing a point each second.
  2. 3. The transfer of thermal energy by direct particle collisions.
  3. 6. The apparent bending of waves as they pass from one medium to another.
  4. 7. The maximum displacement from equilibrium for a transverse wave.
  5. 8. An increase in wave amplitude when a system is driven at its natural frequency.
  6. 9. Energy transferred because of a temperature difference.
  7. 11. The speed at which a wave travels through a medium (4/5).
  8. 14. A wave in which particles vibrate perpendicular to the direction of travel.
  9. 15. The distance between two consecutive crests or compressions.
  10. 16. The transfer of thermal energy by electromagnetic waves.
  11. 17. The maximum displacement of a wave from its equilibrium position.
  12. 20. When two or more waves overlap to produce a resultant wave.
  13. 21. The minimum displacement from equilibrium for a transverse wave.
Down
  1. 2. The transfer of thermal energy by the movement of fluids.
  2. 4. The transfer of energy through matter without the transfer of matter itself.
  3. 5. The change in frequency caused by relative motion between the source and the observer 7/6).
  4. 10. A region of high pressure in a longitudinal wave.
  5. 12. A wave in which particles vibrate parallel to the direction of travel.
  6. 13. A region of low pressure in a longitudinal wave.
  7. 18. The time taken for one complete wave cycle.
  8. 19. The spreading of waves as they pass through a gap or around an obstacle.
