Medium frequency (MF) refers to radio frequencies (RF) in the range of 300 kHz to 3 MHz. Part of this band is the medium wave (MW) AM broadcast band. The MF band is also known as the hectometer band or hectometer wave as the wavelengths range from ten down to one hectometers (1,000 to 100 m). Frequencies immediately below MF are denoted low frequency (LF), and the next higher frequencies are known as high frequency (HF). It is used for AM radio broadcasting, navigational radio beacons, and maritime ship-to-shore communication, among other uses.

Famous quotes containing the words medium and/or frequency:
“The truth is that literature, particularly fiction, is not the pure medium we sometimes assume it to be. Response to it is affected by things other than its own intrinsic quality; by a curiosity or lack of it about the people it deals with, their outlook, their way of life.”
—Vance Palmer (1885–1959)
“One is apt to be discouraged by the frequency with which Mr. Hardy has persuaded himself that a macabre subject is a poem in itself; that, if there be enough of death and the tomb in one’s theme, it needs no translation into art, the bold statement of it being sufficient.”
—Rebecca West (1892–1983)
