Across
  1. 1. The height of a wave from its resting point
  2. 7. the change in direction of a propagating wave (light or sound) when passing from one medium to another
  3. 9. forced vibration by another object
  4. 10. When two waves overlap and make a bigger wave
  5. 12. Time taken to complete one cycle
  6. 13. The emission of electrons from a metal when light shines on the metal
  7. 19. forcing something to vibrate
  8. 20. frequency that the object wishes to oscillate
Down
  1. 2. frequency shift due to motion
  2. 3. The length from one crest to the other
  3. 4. motion that repeats the cycles
  4. 5. high-low
  5. 6. How quickly a wave passes
  6. 8. speed How fast the wave was moving
  7. 11. The lowest point on a wave
  8. 14. wave a wave in which vibration of the medium is parallel to the direction the wave travels
  9. 15. The highest point on a wave
  10. 16. Occurs when an object causes a wave to change direction and bend around it
  11. 17. the bouncing back of a wave after it strikes a barrier
  12. 18. wave Displacement perpendicular to wave direction (ocean light)
