WebThere are two main technologies for turning sound waves into radio waves: AM and FM. AM, or Amplitude Modulation, works by modulating the amplitude "power" of the radio wave in response to the peaks and valleys of the sound wave. FM, or Frequency Modulation, combines two waves: the carrier and the sideband. One wave has a constant frequency. WebDec 22, 2011 · Some of these waves are called radio waves. Radio waves are a type of electromagnetic radiation, a kind of energy that also includes visible light. Radio waves are not harmful but are in fact ...

WebJul 23, 2007 · Others are generated by humans, such as radio waves for communication, microwaves for cooking and X-rays in medicine. Some radiation, like sound waves, needs something to travel through, like air or water. Ultrasound is a medical imaging technique that uses sound waves in the range above human hearing. WebOct 6, 2024 · 1. The Basics. At its simplest, space communications relies on two things: a transmitter and a receiver. A transmitter encodes a message onto electromagnetic waves through modulation, which changes properties of the wave to represent the data. These waves flow through space toward the receiver. The receiver collects the electromagnetic … WebThe microwave auditory effect, also known as the microwave hearing effect or the Frey effect, consists of the human perception of audible clicks, buzzing, hissing or knocking induced by pulsed or modulated radio frequencies.The perceived sounds are generated directly inside the human head without the need of any receiving electronic device.
