Alright kiddo, so let's start with understanding what television channels are. You know how there are different shows on TV that you can watch, like your favorite cartoons or movies? Well, each of these shows is broadcasted on a specific channel, like Cartoon Network or Disney Channel, so that you know where to go to watch them.
Now, when these channels are broadcasted, they use a special kind of energy called radio waves that travel through the air to reach your TV. Think of it like a super-special kind of invisible light that only TVs can see.
But, in order for all the different channels to use these radio waves without interfering with each other, they each use a different frequency, which is like their own special channel of energy. Just like how you have your own unique set of fingerprints or a special secret code, each TV channel has its own unique frequency that it uses to broadcast its shows.
So, when you turn on your TV and change the channel, your TV is basically tuning in to a different frequency so it can pick up the specific shows broadcasted on that channel. And that's how you get all your favorite shows at the touch of a button or remote!
