Lesson 1: Laws of Reflection

🔹 Lessons

1. Laws of Reflection

   • Explanation of reflection

   • Incident ray, reflected ray, normal

   • Laws: i = r and all rays lie in the same plane

2. Spherical Mirrors

   • Types: Concave & Convex

   • Principal focus, radius of curvature, pole

   • Uses of mirrors in real life

3. Mirror Formula & Ray Diagrams

   • Formula: 1/f = 1/v + 1/u

   • Sign conventions

   • Image formation diagrams

4. Refraction of Light

   • Definition

   • Laws of refraction (Snell’s Law)

   • Examples: coin in water, pencil in glass

5. Lenses and Their Applications

   • Convex & Concave lenses

   • Ray diagrams for image formation

   • Uses in spectacles, cameras, microscopes
