A radio wave with a frequency of 32 kHz belongs to which frequency band?

A radio wave with a frequency of 32 kHz belongs to which frequency band?

• A. HF band
• B. LF band
• C. VHF band
• D. UHF band

Answer: (B)

The frequency of 32 kHz falls within the Low Frequency (LF) band, which typically ranges from 30 kHz to 300 kHz. This band is primarily used for applications such as long-distance communication and navigation. In radio terminology, frequencies lower than 300 kHz are categorized into low frequency, and since 32 kHz is well within this range, it correctly identifies the wave as belonging to the LF band. The other frequency bands mentioned do not overlap with 32 kHz. The High Frequency (HF) band starts from 3 MHz and goes up to about 30 MHz, which is far above 32 kHz. The Very High Frequency (VHF) band ranges from 30 MHz to 300 MHz, and the Ultra High Frequency (UHF) band starts from 300 MHz and extends up to several gigahertz. Therefore, only the LF band accurately describes a frequency of 32 kHz.
