How Do AM/FM Radios Work?
The Science of Radio Whether you’re talking AM/FM radio or any of the many other devices that operate using radio waves, the basic science of radio technology is the same. A radio wave is a naturally-occurring phenomenon that can be used to transmit more types of information than just sound. In fact, radio waves are the foundation of all types of modern wireless technology, including cellular phones and WiFi Internet. This is because all of these devices work by decoding information that has been turned into an electrical signal, which can be carried by a radio wave. A radio works by converting this data into a sine wave, which is a type of electronic signal based on oscillating electrical current — in other words, a kind of current that changes between two points of high and low voltage. Radio waves will naturally affect all conductive materials within their vicinity because they cause a motion of electrons in all directions. In order to transmit a specific radio signal, this phenome
