Radio frequencies occupy the range from a few hertz to 300 GHz, although commercially important uses of radio use only a small part of this spectrum. 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.

Famous quotes containing the words radio and/or band:
“All radio is dead. Which means that these tape recordings I’m making are for the sake of future history. If any.”
—Barré Lyndon (1896–1972)
“What passes for identity in America is a series of myths about one’s heroic ancestors. It’s astounding to me, for example, that so many people really seem to believe that the country was founded by a band of heroes who wanted to be free. That happens not to be true. What happened was that some people left Europe because they couldn’t stay there any longer and had to go someplace else to make it. They were hungry, they were poor, they were convicts.”
—James Baldwin (1924–1987)
