Across
  1. 4. The specific direction that a transverse wave is vibrating
  2. 7. Frequency How many waves are created every second. Measured in Hertz (Hz)
  3. 8. waves A transverse wave of pure energy that can go through both a medium and empty space (vacuum). Light is this kind of wave.
  4. 10. The highest point on a transverse wave
  5. 11. wave A type of wave where the medium moves perpendicular (vertical) to the direction the energy is moving.
  6. 15. wave A type of wave where the medium moves parallel (horizontal) to the direction the energy is moving. Sound is this type of wave.
  7. 17. The distance between two similar parts of a wave
  8. 18. The lowest point of a transverse wave
  9. 19. When a wave changes direction because it goes into a new medium
Down
  1. 1. The parts of a longitudinal wave that are spread apart
  2. 2. The parts of a longitudinal wave that are closest together
  3. 3. The maximum distance from the rest position that the medium moves in a wave
  4. 5. The number of waves produced in a given amount of time.
  5. 6. Totally empty space (no medium). Sound cannot travel through this
  6. 9. When one wave hits another wave, their amplitudes combine and make a new wave
  7. 12. A repeated back and forth or up and down motion that gives energy to a wave. Also called "oscillation"
  8. 13. The material a mechanical wave moves through
  9. 14. When waves spread out to fill the space through which they are moving
  10. 16. Wave a disturbance in matter that carries energy from one place to another
