~ ~ ~ ~ ~ ~ ~ ~ ~ ~ Radio waves are a form of electromagnetic radiation, created whenever a charged object accelerates with a frequency that lies in the radio frequency (RF) portion of the electromagnetic spectrum. This is the range from a few tens of hertz to a few hundred gigahertz. ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ Other types of electromagnetic radiation, with frequencies above the RF range are infrared, visible light, ultraviolet, X-rays and gamma rays. Since the energy of an individual photon of radio frequency is too low to remove an electron from an atom, radio waves are classified as non-ionizing radiation.
