The frequency 25 MHz lies in which RF band?

The frequency 25 MHz lies in which RF band?

• A. High Frequency
• B. Very High Frequency
• C. Ultra High Frequency
• D. Super High Frequency

Answer: (A)

Understanding RF bands is about where a frequency sits in the standard frequency ranges. High Frequency typically covers about 3–30 MHz, Very High Frequency 30–300 MHz, Ultra High Frequency 300–3000 MHz, and Super High Frequency 3–30 GHz. A frequency of 25 MHz falls between 3 and 30 MHz, so it is in the High Frequency band. For intuition, 25 MHz corresponds to a wavelength of roughly 12 meters, which aligns with HF characteristics. It’s not in the higher bands because those start at 30 MHz (VHF) and well above. This makes High Frequency the correct classification.
