Knowledge and Understanding
Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:
- Understand the concepts of a good quantum number and simultaneous observability.
- Understand the origin of line widths and shapes in atomic spectra.
- Understand the quantum numbers, including their physical significance, and quantum mechanical states of the hydrogen atom.
