Vibrations and Waves appear in many parts of physics, ranging from simple mechanical systems, to the light that we see, and even to the quantum realm. In this course we develop a fundamental grounding in this important topic, beginning with oscillations of simple systems of discrete masses, continuing with waves in continuous systems (like air and water), and exploring the wave behavior of light. We end with the uncertainty principle and the wave equation of quantum mechanics.
