Refraction Laws Class 10 Physics | One Shot Full Chapter | Light: Reflection and Refraction

In this Class 10 Physics One Shot video, we cover everything you need to know about the Laws of Refraction. Whether you are preparing for your CBSE board exams or just revising the chapter Light: Reflection and Refraction, this video breaks down the concepts simply and quickly. [Key Topics Covered] What is Refraction of Light? The First Law of Refraction The Second Law of Refraction (Snell's Law) Refractive Index explained Important Board Exam Questions [00:00] - Introduction What the video covers and the promise to clear all doubts about Refraction. [00:21] - What is Refraction? Definition of refraction and bending of light when moving between media. [01:33] - Rare vs. Denser Medium Explanation of optical density and how light bends (Towards/Away from Normal). [02:14] - Cause of Refraction Why refraction happens (Speed of light changes in different media). [03:33] - Refractive Index (Absolute) Definition and formula of Absolute Refractive Index (c/v). [05:08] - Relative Refractive Index Understanding refractive index between two specific media (v1/v2). [06:25] - Important Formulas List Summary of all key formulas for solving numericals. [09:10] - Factors Affecting Refractive Index How nature of medium, temperature, and wavelength affect refractive index. [09:52] - Wavelength & Refractive Index Relation Detailed explanation of why Red bends less and Violet bends most. [12:42] - Laws of Refraction The First Law (Plane of incidence/refraction). [13:45] - Snell's Law (Second Law) Detailed explanation of sin i / sin r = constant. [16:50] - Conditions for No Refraction When does light NOT bend? (Normal incidence & same refractive index). [18:23] - Refraction Through a Glass Slab Diagram and explanation of incident, refracted, and emergent rays. [20:20] - Factors Affecting Lateral Displacement How thickness, angle of incidence, and refractive index change displacement. [22:38] - 2025 Board Exam Question Solved Solving a conceptual question on lateral displacement and speed of light.
