This module introduces the quantum description of matter and radiation. The theoretical and experimental background to the de Broglie equations is summarised and from these relationships the time-dependent and time-independent Schrodinger equations are obtained. The wave-functions which provide solutions to these equations are interpreted. Schrodinger's equation is applied to a particle in a box, a simple harmonic oscillator, scattering by a potential well and the penetration of a potential barrier. The two-particle problem is used to introduce the concept of parity. The full quantum solution of the hydrogen atom is then derived.
After taking this module students should be able to:
