Ray Optics Lecture 4 | Real Depth & Apparent Depth | Class 12 Physics | CBSE & NEET

Welcome to Lecture 4 of Ray Optics and Optical Instruments. In this lecture, we will study the important concept of Real Depth and Apparent Depth, which is based on refraction of light at a plane surface. This topic is frequently asked in CBSE Board Exams and NEET. Topics Covered: ✅ Real Depth ✅ Apparent Depth ✅ Apparent Shift ✅ Refraction at Plane Surface ✅ Objects Seen Under Water ✅ Refractive Index Relation ✅ Important Numericals & PYQs Important Formulae: Real Depth / Apparent Depth = Refractive Index μ= Apparent Depth Real Depth ​ Apparent Depth: Apparent Depth= μ Real Depth ​ Apparent Shift: Apparent Shift=Real Depth−Apparent Depth In This Lecture: 🔹 Why does a coin appear raised in water? 🔹 Why do swimming pools look shallower than they actually are? 🔹 Short tricks for NEET and Board Numericals 🎯 Useful For: Class 12 CBSE NEET 2027 JEE Main School Exams Competitive Exams 🏫 KYT Classes Like 👍 Share 🔄 Subscribe 🔔 #RayOptics #RealDepth #ApparentDepth #Class12Physics #NEETPhysics #KYTClasses
