Why The Internet Runs on Light, Not Electricity 🌐💡

Fiber-optic cables use ultra-pure glass to guide light.
The light reflects inside the cable, staying trapped as it travels.
Data is sent as rapid light pulses instead of electricity.
Because light moves fast and loses very little signal, fiber can carry huge amounts of data across the world with almost no delay.
The internet runs on light, not electric wires.
