Particle in a Box Part 1: Solving the Schrödinger Equation

The video tutorial explains how to solve a quantum problem using the Schrodinger equation. It covers the concept of potential, particularly in the context of a particle in an infinite square well, also known as the particle in a box. The tutorial details the process of finding wave functions that satisfy the Schrodinger equation and the boundary conditions of the problem. It includes solving a second-order differential equation, understanding the graphical representation of wave functions, and the concept of quantization. Finally, it discusses the normalization of wave functions and the calculation of eigenenergies.
