Fundamentals of Geometrical and Physical Optics

Optics is the backbone of modern technology, powering everything from medical imaging to global fiber-optic communication networks. This text-based course demystifies how light behaves, travels, and interacts with the physical world. You will gain a clear, intuitive understanding of both ray-based and wave-based light physics through structured, easy-to-follow written explanations. What you'll learn: - Understand the core principles of light propagation, reflection, and refraction. - Analyze image formation using mirrors, thin lenses, and basic optical systems. - Explore wave phenomena including superposition, interference, and diffraction patterns. - Examine polarization and how light waves interact with different materials. - Discover modern practical applications of optics, such as fiber optics and laser fundamentals. This course begins with essential definitions and foundational concepts of geometric ray tracing before transitioning into the wave-based realm of physical optics. It is designed specifically for beginners, students, and technology enthusiasts who want to build a strong physical foundation without requiring advanced mathematics.
