How Light Bends, Splits & Reflects Inside a Prism | Prism and TIR Class 12 Physics

Welcome to Noble Education! 📚⚡ In this lecture, we will understand *Prism and Total Internal Reflection (TIR)* for Class 12 Physics in a simple, visual, and exam-focused way. This topic is an important part of Ray Optics and helps students understand how light bends, deviates, disperses, and reflects completely inside transparent materials. In this lecture, you will learn: ✅ What is a prism? ✅ Refraction of light through a prism ✅ Angle of prism and angle of deviation ✅ Minimum deviation condition ✅ Important prism formulas ✅ Dispersion of white light ✅ What is Total Internal Reflection? ✅ Conditions required for TIR ✅ Critical angle and refractive index relation ✅ Applications of TIR in optical fibres and prisms ✅ Important diagrams and numerical concepts ✅ Common mistakes students should avoid Prism and TIR become easy when you understand the path of light rays step by step. This lecture will help you build strong concept clarity, improve diagram-based understanding, and solve exam questions with greater confidence. Watch the full lecture carefully, revise all important formulas, and practice the examples along with the explanation. 📌 Stay connected with Noble Education for clear concepts, smart learning, and exam-focused preparation.
