  1. For Your Enjoyment Lightning

  2. Composition • Main components • 78% Nitrogen • 21% Oxygen • 1% Argon • Trace components • Carbon dio/monoxide • Krypton • Hydrogen • Helium • Nitrous oxide • Neon • Methane • Ozone • Iodine • Nitrogen Dioxide • Ammonia

  3. Gas Discharge Lamps • Common example: fluorescent lightbulbs • Electric current travels through a tube • The travelling electrons excite the electrons in the gas atoms/molecules. When the electrons move back to lower state, they emit EMR. • EMR is usually in the visible light area but sometimes UV rays are emitted.

  4. Mercury • Mercury emits a bright light. • Light blue • RGB combine to form mostly white light. • Commonly used • Esp. with argon

  5. Nitrogen • Similar to Argon, but duller and more pink. • Argon is violet to pale lavender blue. • Becomes bright blue-white at high peak currents.

  6. Oxygen • Violet to lavender • Dimmer than argon

  7. Argon • Violet to pale Lavender blue. • Often used together with mercury in lamps.

  8. Carbon Dioxide • Bright-white • Brighter than Xenon in lower currents • Xenon is used in car headlights. • Impressive!
