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:
“We spend all day broadcasting on the radio and TV telling people back home whats happening here. And we learn whats happening here by spending all day monitoring the radio and TV broadcasts from back home.”
—P.J. (Patrick Jake)
“And the heavy night hung dark
The hills and waters oer,
When a band of exiles moored their bark
On the wild New England shore.”
—Felicia Dorothea Hemans (17831835)
