Across
  1. 2. falling beam of light on a surface
  2. 4. passing of light through matter
  3. 6. matter that transmits light but also scatter the light as it passes through
  4. 9. matter that does not transmit any light
  5. 11. red, green, blue
  6. 14. light beam reflect off all the points of the surface at the same angle
  7. 17. The idea that liht can act aseither particle or waves
  8. 18. release of light energy by particles of matter that have absorbed energy
  9. 20. “beyond violet” and have shorter wavelengths and higher frequencies than visible light
  10. 21. two primary colors are mixed
  11. 22. “below red” and emitted by the sun
  12. 23. narrow range of wavelengths that humans can see
  13. 24. waves combine and have a greater amplitude than individual waves had

  16. 28. shorter wavelengths and higher frequencies than radio waves
Down
  1. 1. bending of waves and barriers or openings
  2. 3. material that give a substance it’s color by absorbing some colors of light and reflecting others
  3. 5. the emission of energy in the form of EM waves
  4. 7. occurs when a wave bounces off an object
  5. 8. waves combine and have a smaller amplitude than individual waves had
  6. 10. matter through which visible light is easily transmitted
  7. 12. cover the wide range of waves in the EM spectrum
  8. 13. light beam reflect in many different angles
  9. 15. states ankle or incidence is equal to the angle of reflection
  10. 16. pigments yellow, cyan, magenta
  11. 19. the entire range of EM waves
  12. 26. bending of waves as it passes ar an angle from one medium to another
