Foundations of Light: Reflection and Refraction

Light is all around us, yet the rules governing how it bounces and bends can seem complex. Understanding reflection and refraction is the key to unlocking how mirrors, lenses, and even modern optical technologies work. This text-based course guides you through the fundamental physics of light, transforming abstract concepts into intuitive, logical principles you can confidently apply to solve problems and understand the physical world. What you'll learn: - Understand the fundamental behavior of light, including the laws of reflection and refraction. - Analyze how light interacts with plane, spherical, concave, and convex mirrors. - Master the mirror and lens formulas to calculate image distance, object distance, and magnification. - Explore the concept of refractive index and how light behaves when transitioning between different media. - Apply sign conventions accurately to solve optical physics problems without confusion. - Discover modern real-world applications of these principles, from fiber optics to smartphone camera lenses. You will start with essential terminology and the nature of light before moving step-by-step through ray diagrams, mathematical formulas, and practical scenarios. Each module reinforces your learning with written examples and conceptual practice exercises. This course is designed for beginners, high school science students, or anyone looking to refresh their physics knowledge. No prior background in optics is required.
