Across
  1. 2. a disturbance that travels through a medium as a longitudinal wave
  2. 4. The low point of a wave.
  3. 6. perception of the frequency of sound
  4. 8. Do not require a medium (ex: light and radio waves)
  5. 13. Unit of measurement for frequency
  6. 15. A means of transferring energy from one point to another
  7. 16. Particles on the wave vibrate perpendicular to the direction that the wave is moving
  8. 17. The number of waves passing each second; it is measured in Hertz
  9. 18. The high point of a wave.
Down
  1. 1. Particles on these waves vibrate parallel to the direction that the wave is moving (through a series of compressions and rarefactions)
  2. 3. Waves add as they meet
  3. 5. Waves will bounce off barriers an angle equal to the angle they strike the barrier
  4. 7. material through which a wave travels
  5. 9. Maximum displacement of a wave from the rest position or the size of the wave or how large the wave is ( the height of the wave)
  6. 10. The waves partly or completely cancel as they pass
  7. 11. Bending of a wave as it passes into another medium
  8. 12. The distance from a point on one wave to the identical point on the next wave (crest to crest)
  9. 14. Require a medium to travel through (Ex: water waves and sound waves)
