Class 10 Physics | Cartesian Sign Convention & Lens Formula Explained | Light Chapter | Lecture 10

Class 10 Physics – Light: Reflection and Refraction (Lecture 10) In this lecture, we discuss two very important topics from the Class 10 Light chapter: Cartesian sign convention and the lens formula. The lecture begins with a clear explanation of the Cartesian plane and sign convention, which is essential for solving numerical problems correctly. After understanding the sign convention, the lens formula is introduced and explained in detail, including its proper application in numericals. This lecture helps students avoid common mistakes related to signs and formula usage in board examinations. The content is completely NCERT-based and highly useful for CBSE Class 10 Board Exam 2025 preparation. Students are advised to revise the sign convention and formula carefully, as they are frequently tested in exams.
