Refraction of light through a triangular glass prism. Derivation of formulae!

Refraction Through a Triangular Glass Prism | Formula Derivation Explained 🔍 In this video, we take a deep dive into the refraction of light through a triangular glass prism, step-by-step! 📐💡 You’ll learn how light bends as it enters and exits the prism, and we derive the key formulas used to calculate the angle of deviation, minimum deviation, and refractive index. Whether you’re preparing for UNIVERSITY, JAMB, WAEC, NECO, or school exams, this lesson breaks it all down with clear visuals and explanations to help you truly understand how prisms work in optics. ✅ Topics covered: • Laws of refraction • Geometry of the triangular prism • Derivation of angle of deviation • Minimum deviation condition • Refractive index formula: n = sin((A + Dₘ)/2) / sin(A/2)
