Definition of Refraction Of Light? |
Bending of light in boundary of 2 transparent substances |
|
|
Dispersion? |
Seperation of white light into rainbow colorsi |
|
|
Index of Refraction (n) |
Amount a transparent medium reduces the speed of light |
|
|
Critical Angle |
Angle of incidence that creates a 90 degree angle of refraction |
|
|
TIR |
Total internal refraction |
|
|
Total internal refraction |
Light rays are trapped in medium (no longer refracted) |
|
|
Different types of TIR |
Diamonds Fibre optics Prisims Mirage |
|
|
Converging (convex) lens |
Thicker in middle, thin on edges |
|
|
Diverging (concave) lens |
Thicker on edges, thinner in middle |
|
|
3 types of lense issues |
Aberation Chomatic Spherical |
|
|
SALT for concave lens |
S: smaller A: upright L: inbetween lens and object T: virtual |
|
|
Iris |
Colored part of eye, controls entering color |
|
|
Pupil |
Black whole, where light enters |
|
|
Sclera |
Whites of eyes, support eye |
|
|
Lens of eye |
Converging lens |
|
|
Cornea |
Transparent bulge over pupil, focus(refract) light into retina |
|
|
Retina |
Internal membrane, converts light into electrical signals |
|
|
Blind spot |
No rods or cones, other eye makes up for it |
|
|
Optic nerve |
Transmits electrical impulses from retina to brain, takes inverted image and flips it |
|
|
Rods |
Detects brightness, BandW, night vision |
|
|
Cones |
Detect color(RGB), ganglion cells, detect movement/patterns |
|
|
Hyperopia |
Far sighted, converging correction |
|
|
Presbyopia |
Form of far-sightedness |
|
|
Myopia |
Near-sightedness, diverging correction |
|
|
Astigmatism |
Cannot focus object |
|
|
Glaucoma |
Group of diseases, effect optic nerve pressure |
|
|
Cataracts |
Clouding in lens due to lack of protein, cant see |
|
|
What variable reps speed of light in vacuum? |
C |
|
|
What variable reps speed of light in medium? |
V |
