How does Wi-Fi transmit data wirelessly across devices?

Wi-Fi sends data from one device to another using invisible radio waves, just like how a speaker sends sound through the air.

Imagine you have a toy walkie-talkie. When you press the button and talk, your voice turns into radio waves that travel through the air until they reach the other walkie-talkie, then it plays your voice back. Wi-Fi works in a similar way, but instead of voices, it sends data, like messages or videos.

Wi-Fi uses a router, which is like a special kind of radio that can send and receive signals. When you connect your phone to the Wi-Fi network, it's like joining a club, the router knows your phone is there, and they start talking through radio waves.

Your phone turns data into radio waves and sends them out. The router catches those waves, changes them back into data, and sends that data to wherever it needs to go, like your computer or tablet.

So even though your devices aren’t touching each other, they can still send messages and share videos, all thanks to invisible radio waves traveling through the air!
