VLFbereiken

VLFbereiken, or Very Low Frequency (VLF) bands, refer to the range of electromagnetic frequencies between 3 kHz and 30 kHz. This frequency range is of particular interest in various fields due to its unique properties and applications. VLF waves can penetrate deep into the Earth and seawater, making them useful for long-distance communication and navigation. They are also employed in geophysical research to study the Earth's interior and ionosphere. VLF signals are used in submarine communication, as they can travel through water and are less affected by surface interference. Additionally, VLF waves are utilized in the study of the Earth's magnetic field and for the detection of underground structures. The International Telecommunication Union (ITU) allocates specific frequency bands within the VLF range for different applications, ensuring efficient and coordinated use of this spectrum. Despite their practical uses, VLF waves are also studied for their potential impact on human health and biological systems, although the scientific consensus on these effects remains inconclusive.
