Electro magnetic |
1. Energy has no medium 2. Transverse 3. Spherical in nature |
|
|
Which light can hurt your eyes |
Higher end light |
|
|
Luminous light |
An object that gives off energy due to accelerated particles. (Ex. Tungsten lightbulbs, neon lights, LED) |
|
|
Illumination |
Object gives off light by reflecting a luminous source. (Ex. The moon) (this light is easy on the eyes) |
|
|
Illuminated |
The ability to "see" an object by the scattering of light. (If you take away the scattering, the light becomes invisible) |
|
|
The basic unit of light intensity |
Candle power (1cd) |
|
|
A lumen |
The amount of light that passes through a sphere one meter wide and one meter long. (It's intensity is indirectly proportionate to the distance^2) |
|
|
Coplaner |
All points are on the same plane |
|
|
Transparent media |
Permits the transmission of light without scattering |
|
|
Translucent media |
Permits the transmission of light with scattering |
|
|
Opaque media |
Does not permit the transmission of light |
|
|
Tool 1 |
If parallel to the principal axis, then through F |
|
|
Tool 2 |
If through the focus, then parallel to the principal axis |
|
|
Tool 3 |
If through the center, then back to the center |
|
|
The flaw of concave mirrors |
Spherical Abberation. (When the mirror extends 180 degrees horizontally, beams of light can't hit the higher and lower portions) |
|
|
Which light/color is faster? |
The lower the frequency, the faster, so red |
|
|
Red + blue + green = |
White |
|
|
The phenomenon when the lens opens to wide and you see rainbow spectrums |
Chromatic Abberation |
|
|
What color lights help with certain chemicals in the brain? |
Red: melatonin Blue: cortisol |
|
|
Rods |
B&W 120m Can't adjust light/dark well Good peripheral view High definition resolution High motion sensitivity High overall sensitivity |
|
|
Cones |
Color 6m 64% red 32% green 2% blue HYPER (meaning it's equal to red) Can adjust light/dark well Bad peripheral view Low definition resolution Low motion sensitivity Low overall sensitivity |
|
|
Borders on the sight spectrum: |
Not definite |
|
|
The shape of light |
Spherical |
|
|
Abbreviation for illumination |
E |
|
|
The 4 traits of an image: |
1. Location 2. Size 3. Inverted? 4. Real or imaginary? |
|
|
Fiber optics |
Think the bottom of the pool story |
|
|
Which color absorbs the most light energy? |
Black |
|
|
The benefit of using a polarized lens |
It can see through glare |
|
|
The handicaps to second surface mirrors: |
1. Collision with sand particles 2. Ricochet off of sand particles 3. Internal reflection 4. External reflection |
