Across
  1. 2. lowest point
  2. 6. moves perpendicular to the direction of the wave
  3. 8. displaces matter in the same direction that the wave is traveling
  4. 9. distance from one crest of the wave to the next crest
  5. 10. the frequency with long-wavelength, slower
Down
  1. 1. high-density area in a longitudinal wave
  2. 3. distance from the rest position to the crest or trough
  3. 4. low-density area in a longitudinal wave
  4. 5. highest point
  5. 7. the frequency with short wavelength, faster
