REFLECTIVE WRITING

April. 27,2009

 

In this process  I learned about how the pwer of light works. I learned about plato's allegory of the cave history of light. and in this process I learned throught the 18 century all the way up to now light bulbs and soo mucsh more was created for the way we see things. what i've learned is how the throught the 1800's when thomas edison created the first light bulb he was just playing around and discovered that he can make light.all the way from.

1879- the first incodesent light bulb was created

1934 the first HID light bulb was created

1938 the first florescent light bulb was invented

1959 the first hallogen light created

1962 metal halide

2962 LEDs

1976 CFL

1989 etc... 

what i would like to learn is why did he want to discover light why did it mean so much to him. why out of everything why would he pick the light bulb. to do?

QUOTE; Genius is one percent inspirational and nintey-nine percent perspiration  *~Edison~*

with wisdom there is knowldge  and when the lightsb shine you should'nt block it you should let your little shine!

 

reflection for tuesday april.28,2009

what i learned today about light

Well the first thing that I learned about light is that its made up of multiple things such as;

1). electromagnetic

2). radiation

and those parts are also made up of multiple parts themselves such as;

 radiation is made up of

a). electric

B). micro

C). x-rays 

when you look at thing the eyes are most sensitive to the color yellow.

I know that lumen is the measure of visible radiation and I know that when you calculate lumens you give much more weight to the yellow portion of the spectrum and much les weight to the blue and red regions. which means that if the light is reflecting and is angled on a specific object than the light shows the yellow in a  more complex way.

                                 VOCABULARY!!!!!!!! and NOTES!!!!!

MAY.1,2009

in this topic they talked about color and some of the abstracts from it. they talked about things like:
additive- color is color in direct light.
subtractive- is color that is color in relation to pigment or to surface that absorbs wavelenghts of color.
refraction- or bent from the original course.
diffraction- in which a wave of light after passing the edge of an opaque or solid object breaks or spreads out instead of continuing in a straight line.
primary-colors that all other colors are derived from them.such as red blue and green.
secondary-mageneta from red green amd yellow.
tertiary-are colors such as yellow-orange, orange-red, red-violet,violet-blue,blue-green, and green-yellow.
gray scale-
achromatic-when none of the areas have any hue.
hue-is the name by which we identify a colorit refers to the pure state of the color.
value-refers to the relative lightness or darknessof a color.it can be best understood by a study of the gray scale.
normal value-which is the value of the hue when it is seen at its highest intensity.
tints-are color value that are lighter than normal values.
chroma-intensity-indicates the brightness or the dullness of a color.
one way to visualize chroma is to imagine a jar of powdered pigment in any hue and sauccr of oil.
a monocromatic color is a color based off  colors taht are both hard and easy to see.
the color of the subject is determained by the color of the light source and the color of the subject.
photographic film records the light as it actually is. your eye/brain however will always correct light back to normal. your brain compensates constantly.
red light rays only contain red because it is primarly color so green light rays only contain green and blue rays only contain blue. again that is because these are the primarly color.
secondary colors-magenta cyan and yellow are considered secondary colors because each one is a mix of two primary colors.
