Refraction of Light: Understanding Lateral & Apparent Shift

Master Refraction of Light in one complete video! In this detailed tutorial, we explain Refraction of Light, Lateral Shift, and Apparent Shift from basics to advanced level with clear explanations, ray diagrams, formula derivations, numerical examples, and real-life applications. Perfect for Class 10, Class 12, CBSE, ICSE, NEET, JEE, and all board & competitive exam students. When light passes from one medium to another, its speed and direction change — this is called Refraction of Light. We cover Snell’s Law (μ = sin i / sin r) in depth, including what refractive index really means, why light bends, and how speed changes between mediums — explained with animations and simple language. What is Lateral Shift? When a light ray passes through a parallel-sided glass slab at an angle, the emergent ray is parallel to the incident ray but shifted sideways. This sideways displacement is called Lateral Shift. We derive the complete formula step-by-step: d = t × sin(i – r) / cos r and explain how lateral shift depends on slab thickness (t), angle of incidence (i), and refractive index (μ). Multiple numerical problems solved inside the video. Apparent Shift (Apparent Depth / Apparent Height) — why does a coin at the bottom of water appear raised? Why do objects underwater look closer? We explain the Apparent Depth formula d' = d / μ with full ray diagram derivation and cover both apparent depth and apparent height cases. What’s inside the video: Complete concept of Refraction of Light Snell’s Law with proof and examples Lateral Shift in glass slab — formula derivation + numericals Apparent Shift / Apparent Depth — derivation, ray diagrams & applications Simple home experiments (glass slab + laser pointer, coin in water) Important points for board exams and entrance tests If you want to build strong concepts in Ray Optics, this is the video for you. Ray diagrams are drawn very clearly so you never forget the concepts. Like, share, and subscribe for more physics tutorials in simple language. Drop a comment — which topic next?
