31. Primary Colors:

32. Primary Colors of Light:
Red
Green
Blue

33. Primary Colors:
Red
Green
Blue
When all three are combined equally they make white light.

34. Primary Colors:
Red
Green
Blue
When all three are combined equally they make white light.
When two are combined equally they make a secondary color.

35. Secondary Colors:

36. Secondary Colors: Yellow (red + green) Cyan (green + blue)
Magenta (red + blue)

37. Secondary Colors: Yellow (red + green) Cyan (green + blue)
Magenta (red + blue)
Any two colors that combine to form white light are called complementary colors.

38. Secondary Colors: Yellow (red + green) Cyan (green + blue)
Magenta (red + blue)
Any two colors that combine to form white light are called complementary colors.
(yellow and blue / cyan and red / magenta and green)

40. Pigments:

41. Pigments:
Pigments are substances that are used to color other materials.

42. Pigments:
Pigments are substances that are used to color other materials.
The primary colors of pigments are cyan, yellow, and magenta.

43. Prisms :What is happening?

44. Prisms :What is happening?
White light enters a prism its speed is changed.

45. Prisms :What is happening?
White light enters a prism its speed is changed.
Each wavelength is effected differently.

46. Prisms :What is happening?
White light enters a prism its speed is changed.
Each wavelength is effected differently.
The longer the wavelength the less bending there will be.

47. Prisms :What is happening?
White light enters a prism its speed is changed.
Each wavelength is effected differently.
The longer the wavelength the less bending there will be.
The shorter the wavelength the more bending there will be.

48. Prisms:

49. Lenses and mirrors:

50. Lenses and mirrors:
Convex:

51. Lenses and mirrors:
Convex: curved or rounded outwardly (like the surface of a globe).

52. Lenses and mirrors:
Convex: curved or rounded outwardly (like the surface of a globe).
Concave:

53. Lenses and mirrors:
Convex: curved or rounded outwardly (like the surface of a globe).
Concave: curved or rounded inwardly (like the inside of a bowl).

54. Lenses: How do they work?
Transparent piece of glass or plastic that refracts light in a predictable way

55. Diverging/Concave lens
A concave lens causes light to diverge, or spread out, making a smaller image

56. Convex lens
A convex lens causes light to converge, or focus, the type of image formed by a convex lens depends on the position of the object in relation to the focal point.
Notice, that was what up is down and what was down is up after the focal point

57. Essential Knowledge, Skills, and Processes
Identify some common optical tools, and describe whether each has lenses, mirrors, and/or prisms in it. These should include:
eyeglasses
flashlights
cameras
binoculars
microscopes

58. Essential Knowledge, Skills, and Processes
Eyeglasses: have lenses
c. Hyperopia (farsightedness)
a. Normal eye
b. Myopia (nearsightedness)
Corrected with concave lens
Corrected with convex lens
No correction needed

59. Essential Knowledge, Skills, and Processes
Flashlight: has lenses and a mirror

60. Essential Knowledge, Skills, and Processes
Cameras: have lenses, mirrors, and a prism

61. Essential Knowledge, Skills, and Processes
Binoculars: have lenses and prisms

62. Essential Knowledge, Skills, and Processes
Microscope: has lenses

63. How have humans used science to engineer technologies that use electromagnetic energy?
1. Use of lasers
Laser:
Powerful energy of light due to concentrating one wavelength (frequency)(color) of light
All energy is lined up

64. Lasers On “same wavelength” In sync with one another (laser)
Flashlight

65. Lasers Uses: Fiber optics Surgery UPC codes
Burning and reading CD’s, DVD’s & optical flash drives
