  4. 12. Back-and-forth motion that produces waves.
  5. 14. A state of matter with a definite shape and volume.
  6. 16. — A sound with a low amount of energy.
  7. 17. Areas in a longitudinal wave where particles are spread apart.
  8. 19. A sound with a high amount of energy.
  9. 20. A state of matter with a definite volume but takes the shape of its container.
Down
  1. 1. The highest point on a wave.
  2. 3. A state of matter that spreads out to fill any container.
  3. 4. The unit used to measure frequency.
  4. 6. A wave where particles move parallel to the direction of travel.
