Ever wondered when wireless telegraphy first blinked into existence?
Imagine you're trying to send a quick message across a river to a friend on the other side without shouting or using a boat.
Picture a scenario where you can send signals through the air, like invisible waves, to convey your message instantly. This concept is known as wireless telegraphy.
Example
You send a signal across the river, and your friend receives it instantly, without any physical connection.
Remember this
The insight is that wireless telegraphy allows instant communication over distances without physical wires.
