AM broadcasting
AM broadcasting is a way to send sound (like music or someone talking) through the airwaves to radios or other devices in people's homes.
Imagine that you are talking to your friend across a big field. Your friend can hear you because the sound of your voice travels through the air to their ears. This is similar to how AM broadcasting works.
To send the sound to radios, a microphone is used to pick up the sound waves (like your voice) and turn them into an electrical signal. This signal is then sent to a special machine called a transmitter, which changes the electrical signal into radio waves that travel through the air.
When the radio waves reach the antenna on a radio, the antenna picks them up and turns them back into electrical signals. These signals are sent to the radio's speaker, which turns them into sound waves again that we can hear.
Different radio stations use different frequencies or channels to send their broadcasts. It's like using different roads to get to different places. This is how radios can receive different stations without everything getting mixed up.
So, AM broadcasting is simply a way to send sound waves through the air to radios so people can hear music or other sounds.
