Artificial sources of light are those created or enhanced by humans. Examples include: Incandescent light bulbs*: These produce light by heating a filament until it glows. Fluorescent lights*: These use electricity to excite mercury vapor, producing UV light that then causes a phosphor coating to glow. LEDs (Light Emitting Diodes)*: These are semiconductor devices that emit light when an electric current passes through them. Lasers*: These produce a highly concentrated beam of light through a process called stimulated emission. Candles and oil lamps*: These produce light through combustion. Send me the next one 📸
