Across
  1. 2. A dotted line drawn perpendicular to the surface of the refracting of reflecting wave
  2. 6. The time for a particle on a medium to make one complete vibrational cycle
  3. 7. There are two types of this
  4. 8. A material that transfers energy
  5. 10. Rate of change in direction and position of an object in motion
  6. 12. It is equal to 1 cycle per second
  7. 13. The change of a wave's direction passing from one medium to another
  8. 14. A surface separating two phases of matter
  9. 15. Radio waves are an example of this type of wave
Down
  1. 1. Measured in Hertz
  2. 3. Distance between the crest/trough and equilibrium
  3. 4. These waves travel through the layers of the Earth
  4. 5. An example of a longitudinal wave
  5. 9. Distance between two crests/troughs
  6. 11. Ultrasound waves are an example of this type of wave
