In this video, we will cover "Optical Instruments", "Angle of View", "Magnification", and "Simple Microscopes", which are important parts of Optical Instruments. This topic is frequently asked in NEET, JEE, and Board Exams. 🔹What are Optical Instruments? – Instruments that enhance the eye's vision (e.g., microscopes, telescopes) 🔹 Angle of View: The angle subtended by an object at the eye The angle increases as the object approaches → it appears larger 🔹 Magnifying Power: The minimum distance of distinct vision (D ≈ 25 cm) 🔹 Simple Microscope: A single convex lens called a magnifying glass The object is placed inside the focus → A virtual, erect, magnified image Magnifying Power: When the image is formed at infinity: When the image is formed at the minimum distance of distinct vision (D): 📌 This lecture is explained in depth based on NCERT. 📌 With diagrams, formulas, and practical examples. 📌 MCQs, numericals, and conceptual questions are frequently asked from this topic in NEET and JEE! ✅ NCERT-Based Explanation ✅ Visual Angle & Magnifying Power ✅ Simple Microscope Working Principle ✅ Two Cases: Image at ∞ and at ∞ ✅ Important for Board Exams 2025-26 ✅ Must Watch for NEET & JEE Aspirants 2026 📢 Previous Video: Dispersion and Rainbow | Lecture 15 – • प्रकाश का वर्ण विक्षेपण एवं इंद्रधनुष | Ra... 🔔 Subscribe Now: / @sciencedeewane_rksh 📌 Playlist: Class 12 Physics NCERT Full Course - • Class 12 Physics NCERT Full Course simple microscope class 12, simple sukshmarshi physics, magnifying power of lens, visual angle in optics, sushil sir physics, class 12 physics chapter 9, ncert physics class 12, ray optics, physics in hindi, board exam 2026, neet physics preparation, jee main physics, optical instruments, magnifying glass working, image at infinity, m = D/f, m = 1 + D/f, compound microscope introduction, #SushilSir #SaralSukshmdarshi #SimpleMicroscope #Class12Physics #Chapter9Physics #NEET2026 #JEE2026 #PhysicsInHindi #MagnifyingPower #OpticalInstruments #BoardExams2026
