ultra low frequency
(electromagnetic radiation, frequency 300 Hz to 3 kHz)
Ultra low frequency (ULF) radiation is electromagnetic radiation
defined by the ITU to be within the frequency range of
300 Hz to 3 kHz.
It is considered within the lower-frequency end of the
radio spectrum, or beyond (i.e., subradio).
It falls between super low frequency (SLF) and very low frequency (VLF).
