Low to Medium Frequencies ELF radio waves, the lowest of all radio frequencies, have a long range and are useful in penetrating water and rock for communication with submarines and inside mines and caves . The most powerful natural source of ELF/VLF waves is lightning, according to the Stanford VLF Group.

The tone of lowest frequency is called the fundamental ; the others, overtones. The frequencies of the overtones may be whole multiples (e.g., 2, 3, 4, etc., of the fundamental frequency, in which case they…
Read moreWhat are very low frequency waves?
Very low frequency (VLF) is a radio frequency band in the range of 3 to 30 kHz with wavelengths from 10 to 100 km . It is also the name of the band designated by the International Telecommunication Union (ITU).
