What does VLF stand for?

Explanation:
VLF stands for Very Low Frequency, a segment of the radio spectrum defined roughly from 3 kHz to 30 kHz. This band is named for its very long wavelengths, which are on the order of tens to hundreds of kilometers. Those long wavelengths have practical uses, such as submarine communications, because they penetrate seawater better than higher-frequency signals. The other expansions—Very Large Frequency, Vacuum Low Frequency, or Variable Low Frequency—are not recognized designations for this RF band.
