2. What is the Dual Nature of Light

3. 1 PT Light modeled as a particle and a wave.

4. What is a massless, small packet of light energy

5. 2 PT A photon.

6. It’s what light carries and transfers.

7. 3 PT Energy

8. Four ways that waves interact providing evidence for the wave model of light.

9. 4 PT Reflection, refraction, diffraction and interference.

10. Evidence for the particle model of light which is the effect that transforms light energy into electrical energy.

11. 5 PT Photoelectric effect.

12. What is the form of the highest frequency of light?

13. 1 PT Gamma Rays

14. Radio waves has the lowest frequency and the ________ wavelength

15. 2 PT Longest

16. Which has the longer wavelength: infrared light or ultraviolet light?

17. 3 PT Infrared light

18. Which has the higher energy: yellow light or green light?

19. 4 PT Green light

20. The seven forms of light, in order from lowest to highest energy.

21. 5 PT Radio waves, microwaves, infrared light, visible light, ultra- violet light, x-rays and gamma rays.

22. The angle of incidence equals the angle of reflection

23. 1 PT Law of reflection

24. It’s what happens to light as it passes from a less dense to more dense medium

25. 2 PT It refracts. (slows down and bends toward the normal line)

26. The coming together of light rays

27. 3 PT convergence

28. The separation of white light into its component colors due to refraction or diffraction.

29. 4 PT dispersion

30. The shape of the cornea and lens in the eye

31. 5 PT convex

32. What is color?

33. 1 PT A range of frequencies representing visible light

34. The primary colors of light

35. 2 PT Red, green and blue

36. Blue + red; blue + green; and green + red

37. 3 PT Magenta, cyan and yellow

38. It’s the absence or absorption of all color

39. 4 PT black

40. This color is bent the least as it passes through a prism

41. 5 PT red

42. These structures, which occur in equal ratios on the retina, respond to different frequencies of visible light.

43. 1 PT Red, green and blue cone cells

44. A material that only allows one plane of light to pass through.

45. 2 PT polarizer

46. Three boundary interactions that occur in a raindrop, which lead to the forming of a rainbow

47. 3 PT Refraction (dispersion), total internal reflection and refraction (dispersion)

48. Fiber optics works because of this phenomenon.

49. 4 PT Total internal reflection

50. It refers to the number of photons that pass through a given area

51. 5 PT Light intensity
