tremendously low frequency
(TLF)
(electromagnetic radiation, frequency below 3Hz)
Tremendously low frequency (TLF) radiation is electromagnetic radiation
with a frequency below 3Hz.
It is generally beyond the typical lower-frequency
limits placed on radio, a range sometimes
called subradio.
It is adjacent to (beyond) extremely low frequency.
