What is radiofreqency (RF) energy?
Radiofrequency (RF) energy is a type of electromagnetic radiation. Electromagnetic radiation consists of waves of electrical and magnetic energy which ‘radiate’ (that is, travel) through space. The number of waves occurring per second is known as the frequency of the electromagnetic radiation and is measured in Hertz (Hz). Radiofrequency electric and magnetic waves occur at a rate of 3 kilohertz (kHz) – 300 Megahertz (MHz) (that is, 3 thousand to 300 million waves per second).
