Have you ever wondered how the internet can be so fast? It's all thanks to fiber optics! 🚀 In this short, we reveal the secret to their incredible efficiency, focusing on the phenomenon of refraction and reflection. The Refractive Index (n): Discover why the fiber's core material is optically denser than the cladding and how this difference is crucial for guiding light. Run and watch the full video I linked to this short! #fiberoptics #speedoflight #light
