Radio Technology
Definition
Radio technology refers to the use of electromagnetic waves for transmitting sound information, such as music or speech, without requiring wires.
Analogy
Imagine if throwing a stone into a pond created ripples that could carry messages. That's similar to how radio technology works - instead of water ripples though, it uses invisible waves (radio waves) traveling through air!
