Spherical Lenses | Lens Formula & Lens Maker’s Formula |Mashood Sir| Class 12 Physics

In this lecture, we study Spherical Lenses and understand two of the most important relations in optics — the Lens Formula and the Lens Maker’s Formula. This video explains: • What spherical lenses are • Convex and concave lenses • Refraction through spherical surfaces • Derivation and meaning of the Lens Maker’s Formula • The Lens Formula and image formation • Sign convention and magnification • Numerical problem-solving approach This lecture is useful for: ✔ Class 10 & 12 Physics ✔ Board examinations ✔ NEET / JEE foundation ✔ Conceptual understanding of optics 📌 Formulas covered: 1/f = 1/v + 1/u 1/f = (n − 1)(1/R₁ − 1/R₂) 📘 Watch till the end for clear concepts and exam-oriented explanations.
