Lecture 3 – Particle in an infinite potential well

This lecture of introductory quantum mechanics introduces the famous particle in an infinitely steep potential well. Introductory concepts, such as; solving the Schrödinger equation; the wavefunction; eigenvalues and eigenfunctions; and the concept of discrete energy levels are introduced. These introductory concepts are key to understanding more important examples in quantum mechanics, such as, the energy levels of an atom.
