Optics Flashcards
What is incandescent light
The production of light due to high temperatures
What is light from electrical discharge
Light produced by an electric current passing through a gas. Electricity causes the gas to glow
What is light from phosphorescence
Producing light by the absorption of uv light and the emission of lower energy visible light over a long period of time
What is chemiluminescence
Production of light from a chemical reaction
What is light from bioluminescence
Chemiluminescence in living organisms. Used for protection from predators and to attract mate or prey
What is light emitting diode
Electric device that allows electric current to flow in one direction only, producing light
What is fluorescence
When an object absorbs UV light and releases the energy as visible light
Light from triboluminescence
When crystals are scratched rubbed or crushed together
Example of incandescence
Incandescent lightbulbs, flames, heating metals, glass
Example of electrical discharge
Neon signs
Example of phosphorescence
Glow in the dark stickers
Examples of fluorescence
Fluorescent Light bulbs
Example of chemiluminescence
Glow sticks
Examples of bioluminescence
Glow worms, fireflies
Examples of triboluminescence
Quartz, certain lifesavers
