Fundamentals of Physics, II (PHYS 201) It is shown how to extract the odds for getting different values of momentum from a generic wave function by writing it as a sum over functions of definite momentum. A recipe is given for finding states of definite energy, which requires solving a differential equation that depends on what potential the particle is experiencing. The particle in a box is considered and the allowed energies derived. 00:00 - Chapter 1. Review of Wave Functions 40:13 - Chapter 2. The Schrodinger Equation 54:20 - Chapter 3.
