Across
  1. 5. a transparent object with at least one curved side that causes light to change direction
  2. 10. waves- a wave in which the disturbance is perpendicular to the direction the wave travels
  3. 11. is the transfer of energy by a wave to the medium through which it travels
  4. 12. a material through which light does not pass through
  5. 14. lens- lens that is thicker in the middle than at the edges
  6. 15. max distance a wave moves from its rest position
  7. 18. allows most light through
  8. 19. is the passage of a wave through a medium
Down
  1. 1. a material that allows almost all light through
  2. 2. the distance between one point on a wave to the same point on the next wave
  3. 3. the bouncing of a wave off a surface
  4. 4. lens- lens that is thicker at the edges than in the middle
  5. 6. the change of the direction of a wave
  6. 7. waves- causes the particles in a medium to move parallel to the direction that the wave travels
  7. 8. mirrors- a smooth or highly polished surface that reflects light in order to form an image.
  8. 9. waves- a wave that only travels through matter
  9. 13. the number of time the pattern repeats in a given amount of time
  10. 16. a piece of glass or other transparent material cut with precise angles and plane faces, useful for analyzing and reflecting light.
  11. 17. a material in which a wave travels
