Across
  1. 3. 2 colors that make white light
  2. 9. Wave changes direction
  3. 10. Wave is taken in
  4. 12. _______ of Refraction. A value calculated from the ratio of the speed of light in a vacuum to that in a second medium of greater density
  5. 15. EM _____ Can travel through matter or empty space. Usually faster than mechanical waves.
  6. 17. Wave changes direction when going through a new medium
  7. 19. Wave bounces off
  8. 20. __________ Aberration. The light that passes through a lens, especially near the edges, is slightly dispersed.
  9. 23. _______ Effect of Light. Dependent on the velocity at which light is moving towards or away from the observer
  10. 24. Transparent material that focuses light to form an image
  11. 26. If the relative motion of the source is away from the observer, the observed f decreases and λ increases
Down
  1. 1. If the relative motion of the source is towards the observer, the observed f increases and λ decreases
  2. 2. _______ Law of Refraction. Used to find index of refraction, angle of incidence, or angle of refraction
  3. 4. colors 3 colors that produce white light when combined
  4. 5. Eye is longer than normal, so the image is formed in front of the retina.
  5. 6. Eye is shorter than normal, so the image is formed behind the retina.
  6. 7. Combinations of 2 primary colors
  7. 8. Wave passes through
  8. 11. EM ______ The transmission of energy through electric and magnetic fields.
  9. 13. Can see up close, but not far away.
  10. 14. Lens. Thinner in the middle than the edges
  11. 16. Wave is spread out in one direction
  12. 18. ________ Internal Reflection. If the incident angle is increased, the light is reflected back into the first medium.
  13. 21. Lens. Thicker in the middle than the edges
  14. 22. Can see far away, but not close.
  15. 25. Wave is spread out in all directions
