1.
amplitude: the height of a wave crest or depth of a wave trough, measured from its rest point
2.
blue + green light: cyan
3.
compression wave: the matter moves back and forth, the wave is moving the same direction as the energy
4.
Concave: caved in, rays converge ). has focal point, thing are upside down and get bigger and when in front of focal point, then flips
5.
Concave lens: small in middle, thick on outsides. makes light diverage
6.
Cones: detect colour
7.
Convex: flexed outwards, rays diverage (, things look smaller but can see around farther
8.
Convex lens: Thick in inside, causes things to converage (magnifiying glass)
9.
cornea: transparent sheild on eye
10.
crest: hightest point of wave
11.
cyan + yellow + magenta: black
12.
electromagnetic radiation: is the transmission of energy in the form of waves
13.
Energy: is the capacity to apply a force over a distance
14.
far sighted: focal point meets behind retina, needs convex lens
15.
force: is a push and pull
16.
frequency: number of repetitive motions
17.
Gamma ray uses: cancer cells
18.
hertz: (Hz) or cycles per second
19.
Infared waves uses: warm things, computer
20.
Iris: coloured muscle
21.
law of reflection: angle of incidence always equals angle of reflection
22.
light (wave): in wave model, is seen as wave that travels through matter and transfers energy
23.
Light travels from air to water....: slows down and bends toward the normal
24.
light travels from water to air....: speeds up and bends away from the normal
25.
medium: the matter the wave travels through
26.
Microwaves uses: telecommunication, heating food, radar
27.
near sightned: focal point meets in front of retina, needs concave lens
28.
Opaque: prevents light from going through
29.
optic never: back of the eye, sends electric signals to brain
30.
Order of electromagnetic scale: radio, microwave, infrared, visible light, ultraviolet, X rays, gamma
31.
Plane mirror: flat mirror
32.
pupil: and opening that allows light in
33.
Radio waves: longest and lowes, broadcasting, MRI
34.
Ray model of light: one explanation of how light behaves (as a ray)
35.
Red: 700, longest wave length
36.
red + blue light: magenta
37.
red + green + blue: white
38.
red + green light: yellow
39.
reflection: when light waves strike an object and bounce off
40.
refraction: is the bending or change direction of a wave as it passes from one material to another
41.
retina: where images are formed
42.
Rods detect: gray, and movement
43.
Sclera: opaque tissue (white part)
44.
spectrum: the range of colours or frequencies of visible light
45.
Translucent: light is scattered
46.
Transparent: can see through easily, light passes through, little reflection
47.
transverse wave: waves moves up and down, perpendicular to the direction the wave travels
48.
trough: lowest point of wave
49.
Ultraviolet waves uses: Sun, CSI
50.
Violet: 400, shortest wave length
51.
visible light: light you can see
52.
wave: a disturbance or movement that transfers energy
53.
wave model of light: one explanation of how light behaves (as a wave)
54.
X ray uses: bones, machines
