Radiogram (message)
Hey kiddo, have you ever heard of a radiogram before? It's a special message that can travel across long distances using something called a radio wave.
Ok, so imagine you want to send a letter to your friend who lives far away. Normally, you would put it in the mailbox and the postman would deliver it. But what if your friend lived really far away, like on the other side of the world? It would take a really long time for the letter to get there.
That's where a radiogram comes in! Instead of using a postman, we use a machine called a radio to send the message. It's like a special phone that can talk to far away places.
But how does the message actually get sent through the radio? Well, we turn the message into a special code called Morse code. Morse code is like a secret language that uses dots and dashes to represent different letters of the alphabet.
So let's say you want to send the word "hello". In Morse code, that looks like this:
- .... . .-.. .-.. ---
See how there are dots and dashes? Each one represents a letter.
We send the Morse code message through the radio waves and it travels to our friend's radio. Their radio translates the Morse code back into regular words and voila! Our message has been delivered super fast over a long distance.
Cool, huh? Radiograms were really important before we had things like email and texting. But even today, people still use radios to send messages, especially in emergencies when other forms of communication might not work.
