L-1 Light Reflection and Refraction | Ch-9 Class 10 Science NCERT | Boards 2027 | Tarif Sir

Welcome to Lecture 1 of Class 10 Science Chapter 1 - Light: Reflection and Refraction. In this lecture, Tarif Sir builds the complete foundation of this chapter from scratch - covering how we see objects, the nature of light, and the laws of reflection - explained with simple everyday examples and diagrams so that numericals and ray diagrams never feel difficult again. What You'll Learn in This Lecture: How we are able to see objects (role of light) Luminous and Non-Luminous objects with examples What is Light - properties of light as an electromagnetic wave Speed of light and why it travels in a straight line Ray of Light, Beam of Light, Parallel, Converging and Diverging beams Transparent, Translucent and Opaque materials Dual Nature of Light - wave theory and particle theory Reflection of Light and key terms - Incident Ray, Reflected Ray, Point of Incidence, Normal, Angle of Incidence, Angle of Reflection Laws of Reflection of Light (First Law and Second Law) Regular Reflection and Irregular (Diffused) Reflection For Mathematics Subscribe    / @sanyambhayana-9th10th   This lecture series is designed for board exam preparation and covers the following boards: CBSE, RBSE, MPBSE, HPBSE, UBSE About the Teacher: Tarif Sir teaches Class 9 and Class 10 Science with a strong focus on concept clarity rather than rote memorization, making even the toughest topics like ray diagrams and numericals simple to understand and easy to remember. Every lecture is structured to build concepts step by step from the basics, ensuring students are fully prepared for their board exams across multiple state and central boards. Tarif Sir's teaching style focuses on real-life examples, interactive questioning, and thorough revision of every concept so that students gain lasting clarity rather than short-term memorization, helping them approach their Class 9 and Class 10 Science exams with confidence.
