What This Document Is
This document presents a focused exploration of the fundamental relationship between electromagnetic (E-M) theory and the properties of light, as taught in a Physical Optics course at the University of Delaware. It delves into the theoretical underpinnings that describe how light behaves as both a wave and a part of the electromagnetic spectrum. This material builds upon core physics principles to explain light’s characteristics and interactions.
Why This Document Matters
This resource is ideal for students enrolled in an upper-level undergraduate physical optics course, or those with a strong physics background seeking a deeper understanding of light’s wave nature. It’s particularly valuable when studying wave phenomena, electromagnetic fields, and the mathematical descriptions of light propagation. Access to this material will enhance your comprehension of more complex optical systems and applications discussed later in the course. It serves as a strong foundation for understanding advanced topics in optics and photonics.
