Sky wave

Okay kiddo, have you ever used a walkie-talkie or seen one before? It's a small device that helps you talk to someone who's far away. But have you ever wondered how the signal travels from one walkie-talkie to another if they're really far apart? That's where the sky wave comes in.

When we want to send a signal from one place to another, we usually use wires or cables. But if there are no wires or cables available, we can use the sky wave. This is like tossing a ball up in the air and watching it come back down - the ball goes up into the air, and then gravity pulls it back down. The sky wave works in a similar way.

Instead of using wires or cables, we send the signal up into the sky with a transmitter. The signal bounces off the ionosphere - a layer of the atmosphere filled with electrically charged particles - and comes back down to Earth. It's like bouncing a ball off a wall and having it come back to you.

So, if you're using a walkie-talkie and your friend is really far away, you can use the sky wave to send your signal to them. It bounces off the ionosphere and comes back down to their walkie-talkie, allowing you to talk to each other even though you're far away.

That's the sky wave, kiddo! It's like bouncing a ball off a wall to talk to someone far away.
