Low or medium frequency refers to a frequency range used by which navigation aid?

Explanation:
Low or medium frequency refers to the radio band used by non-directional beacons. Non-Directional Beacons operate in the LF and MF bands, transmitting continuous signals that are picked up by an Automatic Direction Finder to determine direction to the station. The other aids—VOR, DME, and TACAN—use VHF or UHF bands, not LF/MF. So the navigation aid associated with low or medium frequency is the non-directional beacon.
