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.
