- 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. ideal shape for a telescopes primary mirror Read Answer Items for Question 4 - 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. mirrors use this Read Answer Items for Question 4 - 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. makes use of crossed Polaroid lenses Read Answer Items for Question 4 - 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. what keeps a light ray inside an optical fiber Read Answer Items for Question 4 - 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. occurs when light passes through a very narrow slit Read Answer Items for Question 4 - 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. occurs when two light waves arrive at a point out of phase Read Answer Items for Question 4 - 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. it is half-silvered Read Answer Items for Question 4 - 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. lens that is thicker at the center Read Answer Items for Question 4 - 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. the image height divided by the object height Read Answer Items for Question 4 - 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. occurs because the speed of light in a transparent substance varies based on the wave length of the light. Read Answer Items for Question 4 Answer 1. constructive interference 2. converging 3. convex mirror 4. destructive interference 5. diffuse reflection 6. diffraction 7. dispersion 8. diverging 9. liquid crystal display 10. magnification 11. one-way mirror 12. parabolic 13. real 14. specular reflection 15. total internal reflectionExplanation / Answer
1) ideal shape --- 12 parabolic (for mirrors > 4 in diameter) to get focus at point
2) mirrors use this ---- 14 specular reflection (definition of specular)
3) crossed Polarod --- 9 could be liquid crystals since they polarize light
4) optical fiber --- 15 total internal reflection keeps light rays within fiber
5) narrow slit ---- 6 diffraction produces fringe pattern
6) light wave phase ----- 4 destructive interference occurs
7) half silvered ---- not sure --- could be 11 one-way since 1/2 light passes thru
8) lens thicker center --- 2 converging lens
9) image height / object height ----- 10 magnification
10) speed of light varies ----- 7 dispersion as white light dispersed by prism
