Across
  1. 2. the distance from the line of origin to a crest or trough. The height of a wave
  2. 5. line running through the center of a wave
  3. 6. lowest point of the wave
  4. 7. empty space
  5. 8. disturbance that propagates through a material medium. Needs a solid, liquid, and gas to travel through
  6. 9. highest point of a wave
  7. 10. number of waves in a given amount of time
  8. 12. mechanical wave propagating through a medium. It vibrates our eardrum so we can hear
  9. 13. a regular pattern of motion that is caused by a disturbance
Down
  1. 1. wave whose vibrations occur in the same direction as its displacement. It moves back and forth
  2. 3. space through which waves travel
  3. 4. do not need a medium to travel through a vacuum (empty space)
  4. 6. mechanical wave propagating sound through a medium. Moves up and down
  5. 11. the distance between 2 consecutive crests.
