🧠 Explanation:

When light passes from a rarer to a denser medium, it bends, a process called refraction of light. For physics students, this highlights optical principles, making it a key topic for studying light behavior, wave properties, and optics applications. Refraction explains phenomena like lenses or rainbows. Understanding it reveals how light interacts with materials, essential for technologies like glasses or cameras. It’s crucial for analyzing wave mechanics, optical engineering, and scientific experiments. Studying refraction offers insights into light’s physical properties, its practical uses, and its role in advancing optical technologies and scientific understanding.
