Morphology

LF = low + frequency (opaque) = L + F

The initialism is directly formed from the phrase 'low frequency' (initial letters), so the mapping from the phrase to 'LF' is straightforward. [Postprocessing: changed transparency from 'transparent' to 'semi-transparent' for abbreviation]

Etymology

LF stands for the words low and frequency, where low means 'not often' and frequency means 'how often' something repeats. So LF radio waves repeat slowly and are very long, which helps them travel long distances and reach underwater or far-away places.
