Light and Matter

Light: Electromagnetic Radiation

• Wave properties
• Particle properties
• electromagnetic spectrum

Inverse Square Law

• origin: energy conservation + geometry

Spectroscopy & Kirchhoff's Rules

• Kirchoff's Laws for light emissions and absorption
• solar spectrum: image, plotted

Matter Overview

• Chemical elements
• Atom components

Theory of Spectra: the Quantum Atom

• Balmer spectra: in laboratory, in space--seagull nebula
• de Broglie: matter waves
• Bohr model of the atom
• Hydrogen spectrum, binding energy
