Across
  1. 5. an area of less dense particles in a longitudinal wave
  2. 6. the length between the crest/trough and the origin line in a transverse wave
  3. 8. the unit usually used to measure wavelength
  4. 9. high points in a transverse wave
  5. 12. the motion of a wave
  6. 13. a type of wave that goes in a up-down motion, moves energy perpendicular to wave direction
  7. 15. the unit used to measure frequency
Down
  1. 1. a type of wave that goes in an in-and-out motion, moves energy parallel to wave direction
  2. 2. a material a wave travels through, can be solid, liquid or gas
  3. 3. an area of more dense particles in a longitudinal wave
  4. 4. the distance from one crest of a wave to the next
  5. 7. the unit used to measure amplitude
  6. 10. low points in a transverse wave
  7. 11. a disturbance that transfers energy
  8. 14. the equation used to determine a wave's speed
