Okay, so you know how sometimes you want to listen to music from the radio or hear someone talking on their radio? A receiver is like the ears of the radio. It helps you hear what's being sent out.
Now, imagine you have a magic spoon that can taste all different flavors of soup. But it only works if you put it in a bowl of soup. The bowl of soup is like the radio waves in the air, and the magic spoon is like the receiver.
When you turn on the radio, the receiver listens for the radio waves that are all around us, just like how the spoon tastes for the soup when you put it in the bowl. Once the receiver picks up the radio waves, it turns them into sound waves that we can hear through the radio.
So basically, a receiver takes in the radio waves and turns it into sounds that we can hear. It's like a magical spoon that can taste all the soup flavors, but for the radio waves in the air.
