Fundamentals of Wave Phenomena

Wave phenomena encompass a broad spectrum of physical systems, wherein oscillations transfer energy and information through various media without the permanent displacement of the medium's particles. This fundamental concept is pivotal in the field of physics as it provides a framework for understanding how waves propagate through different environments—whether they be mechanical, electromagnetic, or quantum in nature.
