Particle in a Box | Physical Chemistry II | 5.1

Physical chemistry lecture introducing the quantum model for translational motion, the 1D particle in a box. This is the simplest non-trivial quantum problem and a great starting point for learning how to build up the Schrodinger equation for a quantum system. Here the physical problem is introduced and the Hamiltonian is explained.

What's the potential at the edge? 0 or infinity? I mean at the boundary??
