(JEE Free Course) Introduction to Refraction | By Ajinkya sir (IIT Madras, JEE AIR 90)

In this lecture, we begin with a Convex Mirror numerical problem and transition into one of the most powerful ideas in optics — Refraction of Light. We break the fundamental belief that “light always travels in a straight line” and understand: ✔ Why light bends ✔ What is optical homogeneity ✔ Wave nature of light (Electric & Magnetic fields) ✔ What happens when light changes medium ✔ Dense vs Rare medium cases ✔ Normal incidence case ✔ Energy distribution in reflection & refraction This is not just formula learning — this is conceptual physics. 🔎 Topics Covered: 00:00 Introduction & Mirror Problem 01:10 Convex Mirror Ray Diagram 03:20 Mirror Formula Application 05:00 Image Position & Size 07:00 Breaking the “Light travels straight” belief 09:30 What is Homogeneous Medium? 11:00 Wave Nature of Light 13:00 Why Refraction Happens (Intuitive Explanation) 17:00 Interface & Angles Defined 20:00 Energy Distribution Concept 23:30 Dense vs Rare Medium Case 26:00 Normal Incidence Case 28:00 What’s Next – Laws of Refraction 📚 Ideal For: Class 9 & 10 Students CBSE / ICSE Boards JEE Foundation NEET Foundation JEE Main
