Many frequency bands have been assigned for specific uses; some of the most commonly used are:
- Very Low Frequency (VLF): 3kHz – 30kHz
- Low Frequency (LF): 30kHz – 300kHz
- Medium Frequency (MF): 300kHz – 3MHz
- High Frequency (HF): 3MHz – 30MHz
- Very High Frequency (VHF): 30MHz – 300MHz
- Ultra High Frequency (UHF): 300MHz – 3GHz
- Super High Frequency (SHF): 3GHz – 30GHz
- Extremely High Frequency (EHF): 30GHz – 300GHz
- Terahertz frequency (THz): 300GHz – 3THz
These bands are used for different purposes, such as radio communication, television broadcasting, satellite communication, radar systems, navigation, and scientific research. As a result, different countries and organizations may have other band allocations, and the specific frequencies within each band may also vary depending on the particular application.
- Microwave band: 1GHz – 100GHz
- Infrared band: 100GHz – 1THz
- Visible light band: 400THz – 800THz
- Ultraviolet band: 100THz – 400THz
- X-ray band: 30PHz – 30EHz
- Gamma ray band: 30EHz – 30ZHz
Certain ones are used for different applications, such as wireless communication, remote sensing, navigation, scientific research, and medicine.
It’s worth noting that these are broad frequency ranges, and the exact frequencies used within each band may vary depending on specific applications and regulations. Additionally, the band names can also vary depending on the source.
These bands are not absolute, and there are overlaps and variations; some of the frequencies within these ranges may not be used for specific applications, and some may not be allowed to be used in certain regions.
- Super Low Frequency (SLF): 3Hz – 30Hz
- Extremely Low Frequency (ELF): 3Hz – 30Hz
