Super High Frequency (SHF) falls within which range?

Super High Frequency (SHF) is defined within the electromagnetic spectrum as the frequency range from 3 to 30 gigahertz (GHz). This frequency range is crucial in various applications, including satellite communication, radar, and microwave technologies. The SHF band is significant because wavelengths in this range allow for high-frequency communication that is capable of transmitting large amounts of data at high speeds.

The range from 3 to 30 GHz is specifically designated according to internationally recognized frequency bands established by organizations such as the Institute of Electrical and Electronics Engineers (IEEE) and the International Telecommunication Union (ITU). Frequencies higher than this range, such as those in the Extremely High Frequency (EHF) range, and frequencies lower than this do not classify as SHF.

The other options fall outside the established parameters for SHF. For instance, 30 - 300 kHz refers to the Extremely Low Frequency (ELF) range, while 300 - 3,000 MHz corresponds to the Ultra High Frequency (UHF) range. Lastly, 30 - 300 MHz is classified as the Very High Frequency (VHF) range. Thus, the correct classification for SHF is definitively from 3 to 30 GHz, making option B
