I learned about many different types of lightbulbs, such as: CFL (compact flourescent light), flourescent, hologen, HID (high-intensity discharge), etc. The HID lightbulbs could reach a kelvin number to reach the amount of kelvins that the sun gives off; which is 5000 kelvin. Neon lights were once known as "liquid-fire".

"The truth shines through the light."

Facts

Edison invented the first lightbulb.

He had more than 1,000 patents.

He invented the Edison Battery.

Paragraph

Today I found out a little about how the eye works. For example, I found out that the retina is made up off two different thihngs, the trons and the cons. They only see black, white, red, blue, and green. The retina makes a mixture of all these different colors and makes the colors we normally see. We found out that the only reason we could see is because of the electromagnetic waves that the light provides.

Words to Know

additive - something that is added, as one substance to another, to alter or improve the general quality or to counteract undesirable properties.

subtractive - tending to subtract; having power to subtract.

refraction - the change of direction of a ray of light, sound, heat, or the like, in passing obliquely from one medium into another in which its wave velocity is different.

diffraction - the phenomenon exhibited by wave fronts that, passing the edge of an opaque body, are modulated, thereby causing a redistribution of energy within the front: it is detectable in light waves by the presence of a pattern of closely spaced dark and light bands (diffraction pattern) at the edge of a shadow.

primary - first in order in any series, sequence, etc.

secondary - belonging or pertaining to a second order, division, stage, period, rank, grade, etc.

tertiary - of the third order, rank, stage, formation, etc.; third.

achromatic -

gray scale - a scale of achromatic colors having several, usually ten, equal gradations ranging from white to black, used in television and photography.

hue - the property of light by which the color of an object is classified as red, blue, green, or yellow in reference to the spectrum.

value - relative worth, merit, or importance: the value of a college education; the value of a queen in chess.

tint - a color or a variety of a color; hue.

shade - the comparative darkness caused by the interception or screening of rays of light from an object, place, or area.

chroma - the purity of a color, or its freedom from white or gray.

intensity - the quality or condition of being intense.

saturation -  The act of saturating, or the state of being saturating; complete penetration or impregnation.

complements - something that completes or makes perfect: A good wine is a complement to a good meal.

split complements -

analogous - having analogy; corresponding in some particular: A brain and a computer are analogous.

monochromatic - of or having one color.

neutral - not taking part or giving assistance in a dispute or war between others: a neutral nation during World War II.

simultaneous contrast

afterimages - a visual image or other sense impression that persists after the stimulus that caused it is no longer operative.

 Neurophysiological processs means that is makes use of both the nervous system and the physiological apparatus for seeing.

Wavelength, Meters

Gamma Rays (10^-14) > X-Rays (10^-10) > Ultra-Violet Rays (10^-8) > Visible Spectrum (10^-6) > Infrared Rays (10^-4) > Radar (10^-2) > Radio Waves, Television (Short wave, broadcast bands, fm) (10²-10⁴) > A-C Circuits

Visible Spectrum = Violet (400 millimicrons) Blue, Green (500 milliomicrons), Yellow-Orange (600 milliomicrons), Red (700 millimicrons)

Color is actually produced by light as it is broken down into electromagnetic vibrations. Variations of the wavelenths of vibrations cause the viewer to see different colors. Isaac Newton proved that Greek philosophers were right in their assumption that color is not a physical property but a matter of perception in 1666.Generally speaking, darkness, inside or out is not black, but a deep grey. The effects of evening light, cloudy days, fog, storms - all of variations in climate and light - have a significant effect on our perception of color.

Additive and Subtractive Color

Most colors seen in everyday life are caused by the partial absorption of white light. A surface we call red will absorb all the reays except those from the wavelenth that produces red, so we percieve red. When light is totally absorbed by a surface, we see black.

Refraction and Diffraction

Light waves passing through the prism are refracted, or bent, from their original course. Colors in a soup bubble or raindrop result from disfraction 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.
