Snell’s Law of Refraction in 59 Seconds!
📘 Snell’s Law of Refraction: JEE Main Concept Simplified Refraction is one of the most common yet crucial topics in optics, especially for JEE Main and Advanced aspirants. Every year, at least 1-2 questions are directly or indirectly based on Snell’s Law . In this post, we’ll break it down in a super simple and quick format, along with formulas, examples, and tips to crack related questions. 📌 What is Snell’s Law? Snell’s Law relates the angles of incidence and refraction with the refractive indices of the two media. 🧪 Formula: n₁ × sin (θ₁) = n₂ × sin (θ₂) Where: n₁ = Refractive index of the first medium θ₁ = Angle of incidence (with the normal) n₂ = Refractive index of the second medium θ₂ = Angle of refraction (with the normal) 🔁 Refraction Rules (Concept to Remember) 👉 Light bends towards normal when it enters a denser medium (higher n) 👉 Light bends away from normal when it enters a rarer medium (lower n) 👉 Speed of light decre...
