Across
  1. 2. Number of seconds per cycle
  2. 4. Waves Waves that need a medium to travel through
  3. 5. Bending of a light wave as it travels through a barrier. The wave will change speed and direction.
  4. 7. Interference Two or more waves at the same place at the same time
  5. 9. Wave Medium moves in the same direction as the energy. Back and forth.
  6. 11. The height of a wave. Measured from rest to crest.
  7. 12. The matter that waves travel through.
  8. 13. Period of time for one cycle; back and forth movement
  9. 16. Caused by reflection of light waves. ie. an optical illusion
  10. 17. Distance from one identical point on a wave to another. ie. Crest to crest or trough to trough.
  11. 19. Interference two waves come in contact; the result is a wave with a larger amplitude
  12. 21. Wave Particles move at right angles to the direction of the waves energy.
  13. 22. Highness or lowness of a sound.
  14. 24. Number of waves that pass a point in one second.
Down
  1. 1. Effect Change in frequency that is due to motion of a source
  2. 3. Interference two waves come in contact; the result is a wave with a smaller amplitude
  3. 6. Bouncing back of a wave. ie. echo or reflection in a mirror.
  4. 8. Waves Waves that do not need a medium to travel through
  5. 10. More dense areas of a wave
  6. 14. Harmonic Motion Back & forth, or repeated motion
  7. 15. Highest point in a wave.
  8. 18. Producing a wave through a medium
  9. 20. Waves A combination of transverse and longitudinal wave
  10. 23. Lowest point of the wave.
