Special points of emphasis

Atomic Theory

The Properties of Light

A basic understanding the quantum nature of light is essential to understanding the early history of Atomic Theory. Without Planck's work, which demonstrated the quantized nature of light, Bohr would not have possessed the analytical framework to interpret the line spectrum of hydrogen. Planck's work introduced the particle/wave model of light that characterizes modern quantum electrodynamics.
