Lectures 20-23: How Lenses Work: Total Internal Reflection to Thin Lens Equations (Remastered)

#ThinLensApproximation #GeometricOptics#ConceptualPhysics In this lecture, we explore the physics of light as it moves through materials with different refractive indices, culminating in the thin lens approximation. The video is divided into three conceptual mini-lectures: Lecture 20: Total Internal Reflection – Learn what happens when light tries to leave a material with a higher refractive index and hits the boundary at a steep angle. Lecture 22: The Thin Lens Approximation – Understand how converging lenses focus light and how to trace image formation using three principal rays. Lecture 23: Thin Lens (Alternative Equation) – Derive an alternative form of the thin lens equation using geometry and learn how to calculate magnification and understand image properties. Whether you're preparing for your first physics exam or looking to revisit the fundamentals, this lecture offers clear explanations and practical insight into geometric optics.
