A receiver that picks up waves that carry sound is called a radio. A radio sends the electric signal through speakers so the sound can be heard. Each radio station sends out radio waves of a certain frequency. A person changes a radio from one frequency to another to hear different stations.
30 Μαΐ 2023 · You can get an idea for how a radio transmitter works by starting with a battery and a piece of wire. A battery sends electricity (a stream of electrons) through a wire if you connect the wire between the two terminals of the battery.
The flow of the electricity creates radio waves that travel out the antenna and travel all the way to your radio. Your radio catches these radio waves which cause an electrical current in your radio. Your radio then turns this current into sound that you can hear!
Radio Principles (Simple) In this article we’re going to explain all the core mechanisms at play that allow radio to function. This is meant to serve as a quick introduction for people who want to get up to speed. A more in depth explanation will come later.
