Class 8 Science | Chapter 13: Light | Full CBSE Lesson by Rishi Sir

*Namaste Students! Welcome back to Gyanu By Rishi Sir.* How do we see the beautiful world around us? Is it just our eyes, or is light the secret ingredient? In today’s final *Class 8 Science (CBSE)* lesson, we explore **Chapter 13: Light**. Using AI-powered 3D visuals and simple experiments, we break down how light behaves, how our eyes work, and how we can care for our vision. 📌 What You Will Learn in This Video: *What Makes Things Visible?* Understanding the interaction between light and objects. *Laws of Reflection:* A detailed look at the incident ray, reflected ray, and the normal. *Rule 1:* The angle of incidence is always equal to the angle of reflection (). *Rule 2:* The incident ray, the normal, and the reflected ray all lie in the same plane. *Regular and Diffused Reflection:* Why a mirror gives a clear image but a wooden table does not. *Multiple Images:* Understanding how mirrors at angles create beautiful patterns, including the science of the **Kaleidoscope**. *Dispersion of Light:* How white light splits into seven colors, just like a rainbow. *The Human Eye:* A deep dive into the anatomy of our eyes, from the *Cornea* and *Iris* to the *Retina* and **Optic Nerve**. *Eye Care:* Essential tips to protect your vision, including the importance of *Vitamin A* in your diet. *The Braille System:* Learning how visually challenged persons read and write using the power of touch. --- 👨‍🏫 Meet Your Educator *Rishi Kumar Garg* I am an educator based in *Ajmer, Rajasthan**, with over **15 years of experience* in the teaching background.
