Total Internal Reflection Class 12 Physics Term 2 Exam 2022 CBSE

Topic: Total Internal Reflection Class 12 Physics Term 2 Exam 2022 CBSE
Chapter: Ray optics and optical instruments.
In this lecture I have discussed total internal reflection class 12 or TIR, which is from ray optics and optical instruments chapter 9 of class 12 Physics ncert. These topics and derivations are covered in the lecture:
1. What is total internal reflection?
2. What is critical angle in total internal reflection?
3. What is the relation between refractive index and critical angle of a medium?
3. What are essential conditions of total internal reflection to take place?
This series is for preparation for term 2 of class 12 Physics of 2022 board exams.
