Class 12 Physics All Board Derivations One Shot LIVE 🔥 | By AIR 15 Shobhit Sir | Part-2

🚨 Class 12 Physics Boards – Complete Derivations ONE SHOT (LIVE) 🚨 Part-1 : https://youtube.com/live/Ap2Om2MvJVE Optics Instruments: https://youtube.com/live/VQskiILiHbs PDF of the Derivations : https://drive.google.com/file/d/1zjhI... Shobhit Sir (✨ AIR 15 ✨) is going LIVE to complete ALL important Class 12 Physics derivations required for CBSE, ISC & all State Boards in one focused, exam-oriented session. This live class is specially designed for students who want clear concepts, strong presentation, and maximum marks in board exams. In this session, derivations will be explained step-by-step, exactly as expected in board answer sheets. You’ll also learn how to structure answers, where students usually lose marks, and how toppers write derivations to score full marks. If you are preparing for boards and want a power-packed revision that actually boosts confidence, this LIVE session is something you should not miss. Learn directly from AIR 15 Shobhit Sir and prepare with the right strategy 🔥 PDF File of the lecture : https://drive.google.com/file/d/1-Mr4... 📚 Chapters Covered in This LIVE Session (Class 12 Physics) -Alternating Current -Ray Optics -Wave Optics -Atoms -Dual Nature of Radiation & Matter -Nuclei Derivations Discussed in this video: -Alternating Current 20.
