Across
  1. 4. the bending of a wave as it passes at an angle from one medium to another.
  2. 5. the entire range of EM waves
  3. 8. states that the level of incidence is equal to the angle of reflection.
  4. 9. the passing of light through matter.
  5. 12. the light you are most familiar with
  6. 13. matter that does not transmit any light.
  7. 14. the very narrow range of wave lengths and frequencies in the electromagnetic spectrum that humans can see.
  8. 18. covers a wide range of waves in the EM spectrum.
  9. 20. if the reflecting surface is slightly rough light beams will hit the surface and reflect at many different angles.
  10. 23. the transfer of energy carried by light waves to particles of matter.
  11. 24. the release of light energy by particles of matter that have absorbed energy.
  12. 28. when two primary colors are added together.
  13. 29. the falling of a beam of light on a surface.
  14. 30. occurs when light or any other waves bounces off an object.
  15. 31. a tiny “packet”of energy that is released by an electron that moves to a lower energy level in an atom.
Down
  1. 1. another type of electromagnetic wave produced by the sun.
  2. 2. the wave interaction that occurs when two or more waves overlap.
  3. 3. the bending of waves around barriers and through openings.
  4. 6. the resulting wave has a smaller amplitude than the original wave had.
  5. 7. if the reflecting surface is very smooth all light beams will reflect off of all the points of the surface at the same angle.
  6. 10. yellow,cyan,and magenta
  7. 11. shorter wavelengths and higher frequencies than radio waves.
  8. 15. carry more information, and music broadcast’s better than AM.
  9. 16. a material that gives a substance it’s color.
  10. 17. the resulting wave has a greater amplitude than the individual waves had.
  11. 19. travel farther than FM waves
  12. 21. red, blue, and green.
  13. 22. matter through which visible light is on easily transmitted.
  14. 25. the range of colors.
  15. 26. waves emitted by the sun.
  16. 27. matter that transmits light but also scatters the light as it passes thorough matter,
