What are radio waves?

Radio waves are invisible messages that travel through the air, just like sound does, but you can't hear them, you have to use a special device to catch them.

Imagine you're playing with a toy phone, and you press a button. A friend across the room hears it because the sound travels through the air. Now imagine instead of sound, you're sending little invisible bumps that travel through the air too, these are radio waves!

Think of radio waves like ripples in a pond. When you throw a stone into water, it makes ripples that spread out. Similarly, when a radio station sends a signal, it creates little ripples (radio waves) that travel far and wide.

Your radio or TV is like a net that catches those ripples, turning them back into sound or pictures, just like your friend hearing the toy phone!

Radio waves are used for music, news, and even cell phones. You don’t need to be close to the radio station; you can listen from anywhere, as long as the radio waves reach your device.

They’re everywhere, just like the air you breathe, but invisible!
