PHYS 302: Vibrations and Waves is an intermediate-level course dealing with vibrations and waves in mechanical, electromagnetic, and quantum contexts. The course addresses free vibrations, forced vibrations, and resonance, leading into normal modes of discrete and continuous systems. Wave propagation is covered for several different types of waves, including electromagnetic waves based on the wave equation (alone—without need for Maxwell's equations) and sound. Similarly, the course deals with wave aspects of matter without requiring quantum mechanics as a prerequisite. This online course is built around downloadable video lectures (various formats), supplemented by web links and downloadable course materials.
