In the context of radio wave propagation, 'lf' stands for 'low frequency,' which refers to electromagnetic waves in the frequency range of 30 kHz to 300 kHz. This range of frequencies is significant because low frequency waves can travel long distances, especially over conductive surfaces and through the atmosphere, making them vital for various communication and broadcasting applications. Their propagation characteristics differ from higher frequencies, leading to unique advantages and limitations in transmission and reception.
congrats on reading the definition of lf. now let's actually learn it.
