The colour of the light that is reflected by an object
What is the definition of additive color mixing?
Working with lights, or on a computer, we begin with black and end with white: the more colors added, the lighter the result
What is the definition of subtractive color mixing?
Working with paint, we begin with white and end with black: the more colours added, the darker the result.
What is the definition of a filter?
A substance that transmits some colors and blocks others.
What is the definition of incandescent?
light produced as a result of high temperatures
What is the definition of electric discharge?
light that is produced from electricity passing through a gas
What is the definition of fluorescent?
light is produced as an object absorbs light energy from it's surroundings and releases is immediatly
What is the definition of phosphorescent?
an object absorbs light energy, stores it, and re-emits it slowly
What is the definition of chemiluminescence?
"cool light" is produced as a by-product of a chemical reaction
What is the definition of bioluminescence?
chemiluminescence in a living organism
What is the definition of triboluminescence?
light produced by pressure, friction, or a mechanical shock
What is the definition of electroluminescence?
Light produced directly from electric energy
What is the definition of laser?
produces light waves at one energy level (one color), the light waves only travel in one direction
What is an example of incandescence?
What is an example of electric discharge?
lightning and neon signs
What is an example of fluorescence?
laundry detergents and highlighters
What is an example of phosphorescence?

What is an example of electroluminescence?
What does Laser mean?
Light Amplification by Stimulated Emission of Radiation
What are the laws of refraction?
Light that moves from a less dense medium to a more dence medium bends towards the normal, that that moves from a more dense medium to a less dense medium bends away from the normal, and light that moves straight on from on medium to another does not bend
