Across
  1. 2. when waves bend around barriers or pass through openings
  2. 3. repeated back and forth or up and down motion
  3. 4. a wave that vibrates the medium at right angles or perpendicular to the direction in which the wave travels
  4. 8. an increase in aplituded of a vibration that occurs when external vibrations match an object's natural fequency
  5. 12. when a wave hits a surface that bounces back
  6. 13. material through which a wave travels
  7. 17. low point on a transverse wave
  8. 18. the interaction between waves that meet
  9. 19. bending of waves due to a change in speed
  10. 20. distance between two corresponding parts of the wave
  11. 21. max distance the medium vibrates from rest position
  12. 22. the number of waves that pass a given point in a certain amount of time
  13. 24. unit of measure for frequency
Down
  1. 1. vibrates the medium in the same direction in which the wave travels
  2. 5. a wave that appears to stand in one place even through it is two waves interfering as they pass through one another
  3. 6. the combination of waves to form a larger amplitude than the individual waves
  4. 7. the combination of waves to form a smaller amplitude than the individual waves
  5. 9. disturbance involving the transfer of energy from place to place
  6. 10. ability to do work
  7. 11. maximum amplitude point
  8. 14. waves that require a medium to travel
  9. 15. a zero amplitude point
  10. 16. high point on a transverse wave
  11. 19. an area where coils are spread out
  12. 23. an area where coils are close together
