Fundamentals of Physics, II (PHYS 201)

The fact that the wave function provides the complete description of a particle's location and momentum is emphasized. Measurement collapses the wave function into a spike located at the measured value. The quantization of momentum for a particle on a ring is deduced.

00:00 - Chapter 1. Review of the Particle Wave Function

11:21 - Chapter 2. Particle on a Ring

56:25 - Chapter 3. The Measurement Postulate
