Study Notes
Light Production Mechanisms
-
Incandescence: Light produced by intensely heating an object. Examples include traditional light bulbs.
-
Electric Discharge: Light generated by passing electricity through a gas. Examples include neon signs.
-
Phosphorescence: Light emitted over time after absorbing energy. Examples include glow-in-the-dark materials.
-
Fluorescence: Light emitted when absorbing ultraviolet (UV) radiation. Examples include fluorescent lights.
-
Chemiluminescence: Light produced by a chemical reaction without significant heating. Examples include glow sticks.
-
Bioluminescence: Light generated by living organisms through biochemical processes. Examples include fireflies and deep-sea fish.
-
Triboluminescence: Light created when certain crystals are physically disturbed, such as scratching, crushing, or rubbing. Examples include cracking sugar crystals.
