Light in practice: (avoid theory here)
- Types of light: normal(incandscent, fluorescent) HID (football stadium lights) New eco-watt fluorescent lights and how they change they way colors look., laser; visible vs infrared
- Properties of light: Spectral characteristics, brightness, color, frequency, coherence, modulation, speed of light
- Light in the Universe: appearance of light after big bang, sources of light, ...
- Light in everyday life: How different light effect humans (depression), everyday sources, human eye
- Light in industry: sources, conversion from/to electricity; some applications of light (laser, ...); application of optics
- Light in science: spectroscopy, astronomy, interferometry (If tht were important, than it should be in those sections)
Light in theory: introduce quantum electrodynamics, explain how the current theory explains light and its applications
History
- Older theories of light
- History of measurement of the speed of light
