VERY LOW FREQUENCY Meaning and
Definition
-
Very Low Frequency (VLF) refers to a range of electromagnetic frequencies commonly used in radio communications and research. VLF signals typically lie in the range of 3 kilohertz (kHz) to 30 kHz, corresponding to wavelengths from 100 to 10 kilometers, and are considered to be at the lower end of the radio frequency spectrum. This frequency band is commonly employed for long-range communication purposes due to its ability to propagate through the Earth's ionosphere, which refracts and reflects higher frequency signals back to the Earth's surface.
VLF signals are used in various applications, including navigational aids, submarine communication, and scientific experiments. For instance, the United States Navy employs VLF communication systems for communicating with submarines at sea, as these signals can penetrate seawater to reach submarines operating at significant depths. Additionally, VLF frequencies are utilized to investigate the Earth's ionosphere, study lightning discharges, and monitor global positioning systems (GPS).
Although VLF signals have limited bandwidth and slower data transmission rates than higher frequency bands, they offer the advantage of superior penetration through water and soil, making them suitable for specific applications. Furthermore, since VLF signals interact with various atmospheric and environmental factors, they are also crucial in monitoring and researching natural phenomena such as earthquakes and magnetic storms. Overall, Very Low Frequency comprises an important frequency range within the radio spectrum that facilitates long-range communication and contributes to scientific exploration.
