Critical angle and Total Internal Reflection complete explanation class 10 ICSE physics

In this video, we will clearly understand the important concepts of Critical Angle and Total Internal Reflection (TIR) in the simplest way. 📘✨ 🔹 What is Critical Angle? The angle of incidence in the denser medium for which the angle of refraction in the rarer medium becomes 90°. 🔹 What is Total Internal Reflection? When light travels from a denser medium to a rarer medium and the angle of incidence is greater than the critical angle, the ray is completely reflected back into the denser medium. In this lesson, I have explained: ✔️ Clear definitions ✔️ Ray diagrams ✔️ Conditions for TIR ✔️ Real-life examples (Optical fibre, mirage, diamonds) ✔️ Important numericals and exam questions This topic is very important for Class 10 & 12 Physics and competitive exams. 👉 Like 👍 Share 🔄 and Subscribe for more easy and powerful science lessons. 📌 Understand concepts deeply, score confidently! #CriticalAngle #TotalInternalReflection #RayOptics #PhysicsClass10 #BarinBoosters
