What is the radio frequency (RF) range?

1kHz to 2GHz
2.4 to 2.5GHz
3kHz to 300GHz
100MHz to 2GHz

The correct answer is: 3kHz to 300GHz

The radio frequency (RF) range is defined as the spectrum of electromagnetic frequencies used for transmitting data wirelessly, and it typically spans from 3 kHz to 300 GHz. This range encompasses various applications such as AM/FM radio, television broadcasts, mobile communications, satellite communications, and other forms of wireless technology. The specified range includes: - Extremely Low Frequency (ELF) from 3 Hz to 30 Hz - Very Low Frequency (VLF) from 30 Hz to 3 kHz - Low Frequency (LF) from 3 kHz to 300 kHz - Medium Frequency (MF) from 300 kHz to 3 MHz - High Frequency (HF) from 3 MHz to 30 MHz - Very High Frequency (VHF) from 30 MHz to 300 MHz - Ultra High Frequency (UHF) from 300 MHz to 3 GHz - Super High Frequency (SHF) from 3 GHz to 30 GHz - Extremely High Frequency (EHF) from 30 GHz to 300 GHz This comprehensive encompassing of frequency ranges makes it essential for various types of wireless communications and electronic systems. Understanding the entire RF range is crucial for professionals working with
