Across
  1. 2. A disturbance that transfers energy from place to place
  2. 4. lines that never intersect
  3. 7. the highest point of a transverse wave
  4. 9. the lowest point of a transverse wave
  5. 11. Material/matter through which a wave travels
  6. 12. where the particles of the medium are close together.
  7. 15. A wave that requires a medium through which to travel
  8. 16. at an angle of 90°; a right angle
  9. 17. the speed at which a wave travels through a medium
  10. 19. a part in a longitudinal wave where the particles are spread apart
  11. 20. straight up and down
  12. 22. Horizontal distance between the crests or between the troughs of two adjacent waves
  13. 23. Occurs when an object causes a wave to change direction and bend around it
  14. 24. Anything that has mass and takes up space
  15. 25. The bending of a wave as it passes at an angle from one medium to another
Down
  1. 1. The bouncing back of a wave when it hits a surface through which it cannot pass.
  2. 3. transverse waves that carry energy without a medium
  3. 5. the height of a wave's crest
  4. 6. the number of complete wavelengths that pass a point in a given time
  5. 8. the place where something begins
  6. 10. to move from one place to another
  7. 13. the ability to do work
  8. 14. Going straight across from side to side
  9. 18. Wave that the particles move backwards and forwards in the same direction as the energy transfer
  10. 21. The position in the wave where particles are not disturbed; half way between the crest and trough.
