2 What is the Dual Nature of Light

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

4 What is a small packet of light energy

5 2 PT A photon.

6 It’s what light carries and transfers.

7 3 PT Energy

8 Evidence for the wave model of light.

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

10 Evidence for the particle model of light.

11 Photons and the photoelectric effect.
5 PT Photons and the 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 It refracts. (slows down and bends toward the normal line)
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 A range of frequencies representing visible light
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 Magenta, cyan and yellow
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 Red, green and blue cone cells
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 Total internal reflection
4 PT Total internal reflection

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

51 5 PT Light intensity
