Fundamentals of Light Phenomena and Geometric Optics

Light shapes our visual world, yet the physical rules governing how light travels, bounces, and bends can seem abstract. This text-based course breaks down essential optical physics into clear, accessible concepts and practical calculations to build your core understanding of light phenomena. Through structured written modules, you will gain a solid grasp of foundational concepts before moving on to practical optical calculations and ray tracing. What you will learn: Understand foundational terminology including light rays, rectilinear propagation, and specular versus diffuse reflection. Apply the laws of reflection and refraction to determine light paths across different optical media. Construct accurate ray diagrams for plane mirrors and various lens types to locate images. Calculate focal length, optical power, and image properties using standard geometric optics formulas. Explore practical applications of optics, including the human eye, optical instruments, and light guides. The course begins with clear definitions and core concepts before progressing to detailed visual ray-tracing explanations and practical physics problems. This course is ideal for beginners and students looking for a straightforward, self-paced foundation in physics without requiring advanced mathematics.
