  light. The Columbia Encyclopedia, Sixth Edition. 2001-05
The term “light” is often extended to adjacent wavelength ranges that the eye cannot detect—to infrared radiation, which has a frequency less than that of visible light, and to ultraviolet radiation and fl light, which have a frequency greater than that of visible light.
Light that is all of the same wavelength and phase (all the waves are in step with one another) is called “coherent”; one of the most important modern applications of light has been the development of a source of coherent light—the laser.
The scientific study of the behavior of light is called optics and covers reflection of light by a mirror or other object, refraction by a lens or prism, diffraction of light as it passes by the edge of an opaque object, and interference patterns resulting from diffraction.

  Light - Wikipedia, the free encyclopedia
Light is electromagnetic radiation with a wavelength that is visible to the eye (visible light) or, in a technical or scientific context, electromagnetic radiation of any wavelength.
The elementary particle that defines light is the photon.
Refraction of light by lenses is used to focus light in magnifying glasses, spectacles and contact lenses, microscopes and refracting telescopes.

Light entering the eye is absorbed by light-sensitive pigments within the rod cells and cone cells in the retina, triggering a cascade of events that creates electrical nerve impulses that travel through the optic nerve to the brain, producing vision.
The constant speed of light predicted by Maxwell's equations contradicted the mechanical laws of motion that had been unchallenged since the time of Galileo, which stated that all speeds were relative to the speed of the observer.
This is a light wave frozen in time and shows the two components of light; an electric field and a magnetic field that oscillate perpendicular to each other and to the direction of motion (a transverse wave).

 Howstuffworks "How Light Bulbs Work"
Before the invention of the light bulb, illuminating the world after the sun went down was a messy, arduous, hazardous task.
Light bulbs are ranked by their power -- the amount of light they put out in a certain period of time (measured in watts).
Incandescent light bulbs give off most of their energy in the form of heat-carrying infrared light photons -- only about 10 percent of the light produced is in the visible spectrum.

Visible light penetrates into the ocean, but once past the sea surface, light is rapidly weakened by scattering and absorption.
Absorption can be caused by phytoplankton which use the light for photosynthesis, particulate matter in the water, dissolved material in the water, or the water molecule itself.
The light energy of some colors is absorbed nearer to the sea surface than the light energy of other colors.

 Modern light
The study of light from ancient Greek times up to the revolutionary breakthrough by Maxwell is studied in the article Light through the ages: Ancient Greece to Maxwell.
Although he could detect no difference in the time taken by the two rays of light, this was put down to his experiment not being accurate enough or that the earth dragged the aether with it in much the same way that it drags the atmosphere.
Lord Rayleigh made an important contribution to light in 1899 when he explained that the sky is blue, and sunsets are red, because blue light is scattered by molecules in the earth's atmosphere.

Light is a small, but important part of the electromagnetic (EM) spectrum.
Light and all EM radiation are composed of small parcels called photons.
The speed of light in air changes with the temperature and pressure and humidity of the air, not enough perhaps for our eyes to detect, but enough to upset sensitive optical instruments.

 Digital Photography Tips - Light Usage
The use of light in a photograph can be the deciding factor of whether that picture will be spectacular or terrible.
In this photo on the left the light is striking the statue's face from the rear right of the camera and this adds more depth to the picture.
In doing this it is important to take your camera light reading off of the background instead of the subject in order for the camera to adjust for an exposure based on the backlight.

 SPACE.com -- Spacewatch Friday: False Dawn: All about the Zodiacal Light
The Zodiacal Light is caused by an enormous cloud of cosmic dust extending outward from the Sun and past the orbit of the Earth.
Hence the reason for the name "zodiacal" light, is because it is usually seen projected against the zodiacal constellations, which were conjured by astronomers and poets to fit the ecliptic.
This is a very faint oval patch of light about 10 to 20 degrees long and 6 to 8 degrees wide (overall, comparable in size to the Great Square of Pegasus) and situated exactly on the ecliptic at that point diametrically opposite to the Sun in the sky.

 Physics4Kids.com: Light & Optics: Introduction
To understand light you have to know that what we call light is only a specific type of light called visible light.
Visible light is near the middle of the spectrum.
Light moves at about 124,000,000 meters per second (less than half the speed in a vacuum) in a diamond.

 Visible Light Waves
When white light shines through a prism or through water vapor like this rainbow, the white light is broken apart into the colors of the visible light spectrum.
Light bulbs are another source of visible light waves.
However, since visible light is the part of the electromagnetic spectrum that our eyes can see, our whole world is oriented around it.

 Light
Light - the primary source of energy for the universe - is the central image of many religions and the photographer's chief resource.
From the relentless power of full sun over water to the beam from a single candle, it is light photographers play with, light in its many moods and manifestations that we capture on film.
Because the character and quality of a photograph can be altered by the character and quality of light, even the most-seasoned photographers puzzle over how a scene should be lit, what lighting angles to use for good results, and what exposure settings will bring out the best detail and tonal shading.

 : Class Light
Light is defined in terms of the red, green, and blue components that combine to create the light color.
Lighting needs to be explicitly enabled with the setEnable method or with the lightOn parameter in the constructor before any of the child light sources have any effect on illuminating the scene.
If lighting is not enabled, the current color of an object in the scene is simply mapped onto the object, and none of the lighting equations regarding Material properties, such as ambient color, diffuse color, specular color, and shininess, are performed.

Street lights are not flbody radiators so you can't even talk about their color temperature.
We expect light to come from above, either because that's where the sun is or because a lot of buildings and houses have overhead lights.
Neil Blatnick, October 16, 2003; 11:32 A.M. For soft lighting, I have used a large (12 - 15 inch) circular clamp (forget what they are called but they are used to help sew patterns onto stretched cloth) with a soft, white, fabric material placed in front of a flash unit (8 inches).

 Howstuffworks "How Light Works"
We are, in fact, seeing light -- light that somehow left objects far or near and reached our eyes.
Light is all our eyes can really see.
The other way that we encounter light is in devices that produce light -- incandescent bulbs, fluorescent bulbs, lasers, lightning bugs, the sun.
