1. Radio waves travel through the air to a receiver. It's the receiver's job to pick up the electromagnetic waves and transform them into sound waves which we can hear with our ears. Electromagnetic waves also transmit the pictures that we receive on our TVs. Also the cell phones we use are electromagnetic devices that get their signal from a tower (or transmit what we say, with electromagnetic waves, to the tower).
