Across
  1. 3. How many wave peaks pass a certain point per given time
  2. 5. faster than the speed of sound
  3. 8. waves that require a medium through which to travel
  4. 9. The bouncing back of a wave when it hits a surface through which it cannot pass.
  5. 10. Bending of a wave as it moves from one medium to another
  6. 11. slower than the speed of sound
  7. 14. For a wave or vibration, the maximum displacement on either side of the equilibrium (midpoint) position.
  8. 15. Highest point of a wave
Down
  1. 1. Occurs when an object causes a wave to change direction and bend around it
  2. 2. Lowest point of a wave
  3. 4. matter in the medium moves back and forth along the same direction that the wave travels, requires a medium, moves energy parallel.
  4. 6. transverse waves consisting of changing electric fields and changing magnetic fields
  5. 7. The distance between a point on one wave and the same point on the next cycle of the wave. ( crest to crest or trough to trough)
  6. 12. a unit of motion that repeats
  7. 13. A wave that moves the medium in a direction perpendicular to the direction in which the wave travels, some transverse waves do not require a medium
