Refraction through a Prism | Class 12 Physics | Ray Optics and Optical Instruments

Описание: ✨ In this NextLeap.AI video, we break down the Refraction of Light through a Prism — from basic geometry to advanced applications like dispersion and minimum deviation.
You’ll learn how light bends twice inside a prism, how the total deviation is calculated, and how refractive index is derived using the minimum deviation method. We’ll also explore dispersion of light and the prism’s dispersive power, with solved examples for exam practice.
This video is a must-watch for CBSE Class 12 Physics students and also highly relevant for JEE/NEET aspirants.
