25
Real image is formed when
Light rays converge at the location of the image
26
Virtual image is formed when
Light rays diverge from a point
27
Index of refraction (n)
The ratio of the speed of light in a vacuum to the speed in a material (c)
28
Index of refraction equation (n)
n = c/v
29
Snells law
nisinθi = nrsinθr
30
How to solve for c using n = c/v
(c = nv)
31
How to solve for v using n = c/v
(v = c/n)
32
Angle of incidence
θi
33
Angle of refraction
θr
34
Critical angle
θc
35
Total internal reflection
If a ray is traveling from a more-dense material to a less-dense material it will bend away from the normal (Occurs when incident angle is larger than critical angle)
36
Critical angle equation
nisinθc = nrsin90 (θc = sin-1 (nr/ni))
37
Converging lens
Focuses parallel rays to a single point and can form a real image
38
Diverging lens
Will always form a virtual image
39
Magnification
The ratio of the image height to the object height (m = hi/ho = - di/do)
40
The mirror/lens equation
1/f = 1/di + 1/do
41
Cornea
A thin protective membrane that refracts light
42
Iris
Controls light entering
43
Pupil
The opening for light
44
Retina
The ‘screen’ on which images are formed (images are always real)
45
Farsightedness
The inability of an eye to focus on near objects (hyperopia) Fixed by converging lens
46
Nearsightedness
The inability of an eye to focus on far objects (myopia) Fixed by diverging lens
47
Plane mirror
Always does virtual upright image
48
Compound microscope contains __ lenses
2 converging lenses
49
Dispersion
Dispersion can occur when white light is refracted
50
Crest/trough
The points of maximum displacement
51
Speed of light in vacuum
3.0 x 108 m/s
52
Types of waves
- radiowaves - microwaves - Infrared waves - ultraviolet rays - x-rays - gamma rays
53
White light
Light is reflected (can be produced by 3 primary colours)
54
Black (light)
Light is absorbed
55
Lens
Refracts light rays to form an image
56
Incandescent
Light produced by an object at high temperature
57
Flourescent
Light produced by substances that are exposed to electromagnetic radiation
58
Phosphorescent
Materials that glow in the dark after being exposed to electromagnetic radiation
59
Chemiluminescent
Light produced from a chemical reaction without a rise in temperature
60
Bioluminescent
The ability of a plant or animal to produce light
61
Triboluminescence
Production of light from friction
62
LED
Light emitting diode transforms electrical energy directly into light energy
