This is the fourth lecture for Chapter 4, where we describe the raising and lowering operators, and their commutation relations.

The course follows the first four chapters of my open book: 
— Wiggins, Stephen (2020): Elementary Quantum Mechanics. figshare. Book. https://doi.org/10.6084/m9.figshare.12928595.v1 

Detailed solutions to all of the problems given in the book can be found here:
