In this video, I have explained the PHY101 GDB Question in a very simple and conceptual way.
Topic is related to optical fiber communication & refractive index change — and how it may or may not affect internet speed & light signals.
📌 Question Discussed:
We use the internet every day through optical fiber cables that carry light signals.
Since light changes its phase when it moves through materials with different refractive indices,
could even a tiny change in an optical fiber’s refractive index disturb your internet speed or signal? Explain.
✔ Concept explained with real-life examples
✔ Optical Fiber & Light Phase Change
✔ Refractive Index & Signal Stability
✔ Practical Internet Communication Insight
✔ VU Students Friendly Explanation
