VLF = V + L + F
VLF is an acronym/initialism: the component letters do not convey semantic content that would allow a learner to derive the meaning from the parts.
Etymology
VLF is a short form for very low frequency, with 'frequency' meaning 'how often' something happens. Think of a slow, deep bass beat that 'wiggles' slowly — that image helps: VLF names radio waves that repeat very slowly and travel far, which is why they are used for submarines and long-distance signals.
