Natural Light Source

The sun

New cards
2

Artificial Light

flashlight

New cards
3

Incandescence

Light bulb

New cards
4

Fluorescence

ultraviolet light

New cards
5

Phosphorescent

glow in dark stars

New cards
6

Chemiluminescence

Glow stick

New cards
7

Bioluminescence

firefly

New cards
8

absorbed

When light is absorbed it, doesn’t pass through the object

New cards
9

transmitted

When light is transmitted it goes through the object

New cards
10

reflected

light bounces off the object

New cards
11

transparent object

a window, this is where light passes through

New cards
12

translucent object

tissue paper, where light sort of passes through

New cards
13

opaque object

a desk because light is absorbed and doesn’t pass through

New cards
14

law of reflection

The angle of incidence is equal to the angle of reflection

New cards
15

Concave Mirror

Images appear larger used for upside down view

New cards
16

Convex Mirror

Images appear smaller and used for bigger view

New cards
17

real vs. virtual image

Real image is where light converges and virtual is where light diverges

New cards
18

why refraction occurs when light moves from air to water

because air is a less dense medium, so when it goes to a denser substance, it bends because it moves slower when going in

New cards
19

Optic nerve

electric signals from eye to brain

New cards
20

Retina

tissue where image is formed

New cards
21

Sclera

white part of eye that maintains eye shape

New cards
22

Ciliary muscle

focusing the eye

New cards
23

Lens

changes direction of light

New cards
24

Iris

the colored part that controls amount of light going in the eye

New cards
25

Pupil

opening where light enters

New cards
26

cornea

it helps focus light

New cards
27

cones

see color

New cards
28

rods

outlines/shapes

New cards
29

aqueous humor

Provides nutrition to eye

New cards
30

virtuous humor

Helps maintain the shape of the eye

New cards
31

the film

retina because image focuses in the eye

New cards
32

the diaphragm

iris because it controls the pupil and how much light enters

New cards
33

the aperture

the pupil because it can adjust itself

New cards
34

the lens

the lens because it focuses light

New cards
35

blind spot

no light sensitive cells so you can’t see from there

New cards
36

hyperopia

eye is too long so you can’t see close up

New cards
37

Myopia

eyes are squished so you can’t see far away

New cards
38

lens is used to correct myopia

the correct lens to use for myopia is a concave lens

New cards
39

lens used to correct hyperopia

The correct lens for hyperopia is convex

New cards
40

lens vs. mirror

lens is when light can pass through and a mirror is when light reflects or bounces off of that surface

New cards

optical technology examples

VR - This helps treat lazy eye by making both eyes work by focusing on a certain thing

Glasses - This helps treat people with poor vision because when using certain lenses, the light will be directed in a certain way that helps your eye

Laser eye surgery - This helps treat poor vision by taking out the corneal tissue to fix it a bit and put it back in the eye to improve it
