Across
  1. 2. passage of a wave through a medium
  2. 3. Maximum distance that the wave is from its rest position
  3. 9. that is thicker at the edges than the middle
  4. 10. material in which a wave travels is called
  5. 12. allows most a light to pass through and objects can be seen clearly
  6. 13. wave that travels only through matter
  7. 16. material through which light doesn't pass through
  8. 17. The color you see depends on the color of light that objects reflects
  9. 20. most light to pass through nut appear blurry
Down
  1. 1. Particle motion is in the same direction in which the wave is propagating
  2. 4. Change in direction of a wave when it travels by the edge of an object
  3. 5. is a wave in which the disturbance is perpendicular to the direction the wave travels
  4. 6. distance between one point on a wave to the same point on the next wave
  5. 7. flat reflective surface
  6. 8. causes the particles in a medium to move parallel to the direction that the wave travels
  7. 11. number of times the pattern repeats in a given time
  8. 14. Lens that is thicker in the middle than at the edges
  9. 15. Transfer of energy by a wave to a medium through which it travels
  10. 18. change of direction of a wave when it changes speed while moving from one medium to another
  11. 19. transparent objects with at least 1 curved side that causes light to change direction
