  1. 2. Waves A combination of transverse and longitudinal wave
  2. 3. Likes to chase mice
  3. 5. Caused by reflection of light waves. ie. an optical illusion
  4. 8. Wave Medium moves in the same direction as the energy. Back and forth.
  5. 13. The matter that waves travel through.
  6. 16. Interference two waves come in contact; the result is a wave with a smaller amplitude
  7. 18. Number of waves that pass a point in one second.
  8. 21. Wave Particles move at right angles to the direction of the waves energy.
  9. 24. Lowest point of the wave.
  10. 25. Bending of a light wave as it travels through a barrier. The wave will change speed and direction.
  11. 26. Producing a wave through a medium
  12. 28. Period of time for one cycle; back and forth movement

  1. 1. Waves Waves that need a medium to travel through
  2. 3. Interference two waves come in contact; the result is a wave with a larger amplitude
  3. 4. Number of seconds per cycle
  4. 6. Has a trunk
  5. 7. Effect Change in frequency that is due to motion of a source
  6. 9. Interference Two or more waves at the same place at the same time
  7. 10. More dense areas of a wave
  8. 11. Distance from one identical point on a wave to another. ie. Crest to crest or trough to trough.
  9. 12. Highness or lowness of a sound.
  10. 14. Man's best friend
  11. 15. Bouncing back of a wave. ie. echo or reflection in a mirror.
  12. 17. Flying mammal
  13. 19. Highest point in a wave.
  14. 20. Waves Waves that do not need a medium to travel through
  15. 22. The height of a wave. Measured from rest to crest.
  16. 23. Large marsupial
  17. 27. Harmonic Motion Back & forth, or repeated motion
