Across
  1. 7. The distance between repeating points like crest to crest
  2. 8. The change in frequency due to movement of source or observer
  3. 13. The material a wave travels through (e.g. air, water)
  4. 14. The highest point of a wave
  5. 15. The lowest point of a wave
  6. 17. Spreading of waves around openings or obstacles
  7. 21. The adding together of wave amplitudes
  8. 22. When waves meet and combine
Down
  1. 1. How fast a wave travels through a medium
  2. 2. When vibrations increase due to matching frequencies
  3. 3. A disturbance that transfers energy from one place to another
  4. 4. A wave type that can travel through empty space
  5. 5. A wave type that requires a medium to travel
  6. 6. The height of the wave; relates to energy
  7. 9. When a wave bounces off a surface
  8. 10. Areas where particles are spread out
  9. 11. Waves where movement is parallel to direction of travel
  10. 12. wave A wave that appears to stay in one place
  11. 16. Areas where particles are close together (longitudinal waves)
  12. 18. How many waves pass a point each second
  13. 19. When a wave changes direction entering a new medium
  14. 20. Waves where movement is perpendicular to direction of travel
