PHY101 GDB | Optical Fiber Refractive Index Concept Explained | VU Fall 2025 | Virtual university |

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 This video is helpful for: — Virtual University Students — PHY101 GDB Understanding — Conceptual Physics Learners — Fall 2025 Students 👇 Comment below if you want ➡ more physics concepts explained ➡ or next GDB / Assignment discussion 👉 Subscribe for more VU & Study Related Content 💛 🔥 Hashtags (Trending + Relevant) #virtualuniversity #virtualuniversitypakistan #virtualuniversityofpakistan #vu #physics #phy101 #PHY101 #Physics101 #GDBSolution #VirtualUniversity #VUFall2025 #OpticalFiber #RefractiveIndex #PhysicsConcepts #StudyWithMe #VUGDB #PhysicsLecture #InternetTechnology 🎯 Tags (SEO Ranking + Search Friendly) phy101 gdb solution physics 101 gdb fall 2025 vu phy101 gdb explanation optical fiber refractive index internet speed optical fiber light phase change physics virtual university physics gdb phy101 vu fall 2025 optical fiber communication physics refractive index effect on light phy101 concept explanation physics gdb urdu hindi vu students guide Phy101 gdb Phy101 gdb kesai karai Phy101 gdb concept PHy101 ki gdb
