Across
  1. 5. objects which emit light on their own
  2. 6. number of different types of EM wave
  3. 13. a copy of the object formed by reflected or refracted rays of light
  4. 14. material that permits light to pass through
  5. 15. Any two colors that combine to form white light
  6. 17. objects that are capable of reflecting light to our eyes
  7. 18. two primary colors combine in equal amounts
  8. 19. result of the combination of blue and green light
  9. 20. color which has the shortest wavelength
  10. 22. result of the combination of blue and red light
Down
  1. 1. happens when light is scattered in different directions
  2. 2. occurs when a wave bounces back after striking a barrier
  3. 3. is transparent optical element with flat, polished surfaces that refract light with at least two non-parallel surfaces
  4. 4. Smooth, shiny surfaces have this type of reflection
  5. 5. angle of incidence is equal to angle of reflection
  6. 7. a material that transmits some light but also scatter light in all directions
  7. 8. result of the addition of blue, red and green light
  8. 9. material that allows no light to pass through
  9. 10. three colors that can combine to make any other color
  10. 11. the portion of the spectrum that our eyes sense
  11. 12. color which has the lowest frequency
  12. 16. bending of waves
  13. 18. are places where light is “blocked”
  14. 21. happens when yellow, cyan and magenta were combined
  15. 23. color formed when yellow and cyan are combined
