Across
  1. 2. Number of waves passing a point in a second
  2. 4. Low-density area in a longitudinal wave
  3. 7. Distance from rest position to crest/trough
  4. 8. A way to measure wavelength, from a lowest point to the next
  5. 9. Type of wave that moves perpendicular to direction of wave
  6. 10. The material a wave travels through to transport energy
Down
  1. 1. Distance from one crest or trough to the next
  2. 3. Type of wave that moves parallel to direction of wave
  3. 5. One way to measure wavelength, from a highest point to the next
  4. 6. High-density area in a longitudinal wave
