What is the LF frequency range?

The LF frequency range, which stands for Low Frequency, is defined as spanning from 30 kHz to 300 kHz. This range is significant in various applications, including AM broadcasting and navigational signals. Low frequency waves can propagate over long distances, especially during night-time, making them suitable for certain communication and broadcasting applications.

In the context of the choices provided, it is clear that the correct interval aligns precisely with this established definition, indicating that option A accurately represents the LF frequency range. Other choices suggest frequency ranges that do not adhere to the standard classification of low frequency, either overlapping with different bands or extending beyond the LF classification. Understanding these designations is crucial for technicians working with radio frequency systems and communications.
