Modeling Geometrical Optics in Excel

Struggling to visualize how light behaves through complex lens systems? Understanding geometrical optics becomes intuitive when you build the mathematical models yourself using spreadsheet formulas. This course bridges the gap between physics theory and practical calculation, helping you master optical concepts step by step. In this text-only course, you will start with foundational definitions of light rays and progress to constructing your own optical calculation sheets. You will read clear explanations of physics laws and learn how to translate them into Excel formulas to solve and simulate optical paths. What you'll learn: - Understand the core principles of light propagation, reflection, and refraction. - Apply Snell's Law and the lens maker's equation using dynamic Excel formulas. - Build interactive ray-tracing models for spherical mirrors and thin lenses. - Analyze multi-lens systems and calculate image magnification programmatically. - Utilize modern Excel features like dynamic arrays to map light paths. - Practice your skills with structured physics exercises and step-by-step formula guides. We begin with basic terminology, sign conventions, and the laws of reflection. From there, you will learn to set up structured sheets to calculate focal lengths, image distances, and magnification for both mirrors and lenses, building up to multi-component systems. This course is designed for physics students, engineering beginners, and educators looking for a practical, hands-on way to study optics. No advanced physics or prior spreadsheet expertise is required. Start building your optical models and master the mechanics of light today.
