How does Wi-Fi transmit data wirelessly across a room?

Wi-Fi sends data through the air using radio waves, just like a phone call uses sound waves to travel from one person to another.

Imagine you have a remote control for your TV. When you press a button, it sends a signal that tells the TV what to do. Wi-Fi is kind of like that remote control, but instead of telling a TV what to play, it sends messages between your phone and the internet, all through the air!

When you connect to Wi-Fi, your device (like a phone or laptop) talks to a special gadget called a router. The router is like a boss who knows how to send messages. When you open an app, like a game or a video, your device sends a message to the router, saying, "I want this!"

The router takes that message and turns it into invisible radio waves, which are like tiny energy signals you can’t see but can feel, just like how your phone vibrates when you get a text.

These radio waves fly through the air and land on your device, where they become the game or video you're watching. It's like sending a letter that travels by airplane instead of by mail!
