Fundamentals of the Reflection of Light

Understanding how light interacts with surfaces is one of the most fundamental concepts in physics, yet grasping the math and geometry behind it can often feel challenging. This written course simplifies the physics of light, breaking down complex optical phenomena into clear, digestible explanations. You will transition from basic concepts to confidently solving reflection problems and drawing accurate ray diagrams. What you'll learn: - Understand the fundamental laws of reflection and how light behaves on different surfaces - Classify the differences between regular and diffused reflection - Construct step-by-step ray diagrams for both concave and convex spherical mirrors - Apply the mirror formula and magnification equations to solve practical physics problems - Identify real-world applications of spherical mirrors in modern technology and daily life This course begins with foundational definitions of light, wave properties, and the behavior of rays on plane surfaces. You will then progress to spherical mirrors, exploring the mathematics of image formation and sign conventions through structured written examples and practice scenarios. This course is designed for beginners, high school physics students, or anyone looking to build a strong foundational understanding of optics from scratch. No prior physics knowledge is required.
