What does VHF stand for in terms of frequency bands?

Very high frequency
Variable high frequency
Visual high frequency
Volatile high frequency

The correct answer is: Very high frequency

VHF stands for Very High Frequency, which is a designation used in radio frequency communication. The VHF range spans from 30 MHz to 300 MHz and is significant in various applications, including television broadcasting, two-way radio communications, and aviation. The frequencies within this band are known for their ability to propagate over relatively long distances and their relatively straightforward transmission characteristics, making them ideal for many forms of communication. The other terms listed refer to concepts that do not accurately define this specific frequency band. "Variable high frequency" suggests a fluctuating range of frequencies, which does not align with the fixed definition of VHF. "Visual high frequency" is not a recognized term in radio communications and does not pertain to frequency bands at all. "Volatile high frequency" implies instability, which is not applicable in the context of defined frequency ranges. Hence, Very High Frequency is the proper and widely accepted term used in telecommunications.
