📘 Spherical Mirrors | Concave & Convex Mirrors | Ray Diagrams | Mirror Formula | Magnification | Class 10 & 12 Physics

Welcome to this detailed and easy-to-understand video on Spherical Mirrors, where we explore Concave mirrors, Convex mirrors, important Ray Diagrams, the Mirror Formula, and the concept of Magnification.
This video is perfect for Class 10, Class 12, NEB, CBSE, NEET, JEE, and all competitive exams.

⸻

🔍 What You Will Learn in This Video

✔️ What are spherical mirrors?
✔️ Difference between concave and convex mirrors
✔️ Formation of images using ray diagrams
✔️ Nature, position, and size of images for different object positions
✔️ Mirror formula:
\frac{1}{f} = \frac{1}{v} + \frac{1}{u}
✔️ Sign convention for mirrors (New Cartesian sign convention)
✔️ Magnification formula for spherical mirrors
✔️ Uses of concave and convex mirrors in daily life
✔️ Numericals and concept-building examples

⸻

🔭 Ray Diagrams Covered

👉 Ray diagram for concave mirror when object is at:
• Infinity
• Beyond centre of curvature (C)
• At centre of curvature
• Between C and focus (F)
• At focus
• Between focus and pole (real & enlarged virtual image case)

👉 Ray diagram for convex mirror:
• Object at infinity
• Object anywhere in front of the mirror
(Always virtual, erect, and diminished images)

⸻

📘 Mirror Formula Explained

The mirror formula relates object distance (u), image distance (v), and focal length (f).
This video explains the formula, its derivation, and how to apply it in solving numerical problems.

⸻

🔢 Magnification Formula

Magnification (m) defines how much bigger or smaller the image appears:
m = \frac{h_i}{h_o} = \frac{-v}{u}
Learn how to use this formula for both concave and convex mirrors with solved examples.

​⁠ ​⁠ elcome to my channel! I’m Sunny Chaurasiya, an Aerospace student, and in this video, we’ll explore an exciting physics concept — Charged Particles in a Magnetic Field 🧲

You’ll learn how a charged particle behaves when it enters a magnetic field, the direction of force using the Right-Hand Rule, and how this motion forms the basis for many scientific and engineering applications — including aerospace systems and particle accelerators.



🎯 Perfect for:
Class 12 Physics | JEE | NEET | Aerospace Aspirants | Competitive Exams
