Across
  1. 4. Distance between a point on one wave and the same point on the next cycle of the wave
  2. 5. Surface particles move in circles
  3. 9. Pair of perpendicular transverse waves (electric field and magnetic field)
  4. 11. type of interference that occurs when two or more waves facing opposite directions combine and the smaller wave destroys part of the larger one
  5. 13. How high or low a sound seems to the human ear
  6. 16. a disturbance that propagates energy through a medium or empty space
  7. 17. Interaction of a wave when it bounces off a surface it cannot pass through
  8. 18. A wave that travels through a medium
Down
  1. 1. How loud or quiet a sound seems
  2. 2. Vibration is perpendicular (right angle, 90°) to the direction of motion
  3. 3. Transverse: The maximum displacement of a particle by a wave measured from its resting position
  4. 6. Vibration propagates (moves) in the same direction as the movement of energy
  5. 7. Material through which a wave carries energy
  6. 8. Apparent change in frequency due to moving objects
  7. 10. type of interference that occurs when two or more waves facing the same direction combine and construct a larger wave
  8. 12. Waves bend as they move around an obstacle or through a narrow opening
  9. 14. The number of complete cycles of the wave in a given time
  10. 15. Time it takes for one complete cycle of a wave to pass a given point
  11. 17. Waves bend when entering a new medium at an angle
