75 Days Crash Course Day-53 | Class 12 Physics | CH-8 Ray Optics | CBSE + ISC | Lecture-3 |

📅 Date: 7th January, 2026 ⏰ Time: 7:30 PM 📚 Class: 12 (CBSE + ISC) 🎓 Subject: Physics 📖 Chapter: Chapter 8 – Ray Optics 🎥 Lecture: 3 📌 Series: 75 Days Crash Course – Day-53 🏫 Batch: Shikhar Batch 👨‍🏫 Teacher: EdufyHub’s Physics Expert Welcome to Day-53 of the 75 Days Crash Course for Class 12 Physics (CBSE + ISC). In Lecture-3, we cover the backbone of optics — Refraction of Light, along with Snell’s Law, which is heavily tested in theory, numericals, and ray-diagram questions. This lecture is crucial for understanding glass slabs, prisms, lenses, and optical instruments, making it one of the most important sessions in Ray Optics. ⭐ Topics Covered in Lecture-3: • Meaning of Refraction of Light • Laws of Refraction • Snell’s Law and its Mathematical Form • Refractive Index (Absolute & Relative) • Refraction through Rectangular Glass Slab • Lateral Displacement (Conceptual) • Board-Oriented Questions & Numerical Approach 🎯 Why This Class Is Very Important: • High-weightage topic in CBSE + ISC boards • Forms the base for lenses, prisms & optical instruments • Frequently asked numericals and ray diagrams • Easy marks with proper conceptual clarity • Fully aligned with CBSE + ISC Board Exam 2026 syllabus 🔔 Stay Connected Subscribe to EdufyHub for daily Class 12 Physics Crash Course lectures, PDFs, PYQs, and smart revision strategies.
