What are tower signals?

Tower signals are messages that travel from one place to another through the air using special tools on top of towers.

Imagine you have a friend who lives far away, and you want to tell them something without shouting or writing a letter. You could use tower signals, like a giant flashlight up high, when you turn it on, your friend sees the light and knows what you're saying!

Think of it like using flashlights in a game of tag. If you're hiding and want to tell your friend where you are, you can shine your flashlight in their direction. Your friend sees the light and knows to go that way.

Tower signals work the same way, but instead of flashlights, they use radio waves, which are like invisible messages that travel through the air very fast. These messages help people talk on phones, watch TV, or play games even when they're far apart, just like you and your friend playing tag with light!
