How Light Bends explores the fascinating physics of refraction, explaining why light changes direction when moving between different materials like air and water. The book explains how this bending affects our everyday experiences, from the distorted view of objects underwater to the captivating display of rainbows. Readers will gain insight into Snell's Law and the index of refraction, key concepts controlling how light behaves, and how these principles underpin various optical phenomena. The book progresses from fundamental principles to real-world applications across three sections. First, it introduces the physics of refraction. Then, it dives into specific examples such as lenses, underwater vision, and mirages. Finally, it explores practical applications in fiber optics and advanced imaging. This approach bridges physics, atmospheric science, and optics, revealing how understanding refraction is vital for both explaining natural occurrences and developing advanced technologies.
