Across
  1. 2. the bending of a wave caused by a change in its speed as it moves to a different medium
  2. 6. wave in which the matter moves perpendicular to the direction the energy travels
  3. 9. waves that do not need a medium to transfer energy
  4. 12. material through which a wave transfers energy
  5. 13. less dense region of a longitudinal wave
  6. 14. measure of energy in a wave
  7. 16. when a wave strikes a barrier and bounces back
  8. 18. wave in which matter in the medium moves parallel to the direction the energy travels
Down
  1. 1. waves that can only travel through matter
  2. 3. the amount of time it takes one wavelength to pass a point
  3. 4. the ability of two or more waves to combine and form a new wave
  4. 5. measure of how many wavelengths pass a fixed point each second
  5. 7. the bending of waves around a barrier
  6. 8. highest point of a transverse wave
  7. 10. region where the medium is dense in a longitudinal wave
  8. 11. distance between one point in a wave to the next nearest point just like it
  9. 15. lowest point of a transverse wave
  10. 17. repeating disturbance that transfers energy through matter or space
