What frequency range is categorized as low frequency radio wave?

The range designated as low frequency radio waves is indeed from 0.03 to 0.3 MHz. This frequency band is part of the larger radio frequency spectrum and is crucial for certain types of long-range communication. Low frequency waves can travel long distances, particularly by following the curvature of the Earth, which enables them to be utilized in applications such as maritime and aeronautical communications, as well as in some types of navigation systems.

The range above 0.3 MHz transitions into the medium frequency band, which covers 0.3 to 3.0 MHz, and then higher frequencies lead into high frequency and very high frequency bands. Each of these bands has different propagation characteristics and uses, which is essential for understanding radio wave behavior in different applications.
