Which frequency range corresponds to Medium Frequency (MF)?

• A. 3 - 30 MHz
• B. 30 - 300 kHz
• C. 300 - 3,000 kHz
• D. 30 - 300 MHz

Answer: (C)

The frequency range that corresponds to Medium Frequency (MF) is commonly defined as 300 kHz to 3,000 kHz, or 0.3 MHz to 3 MHz. This range is significant in radio communication as it is primarily used for AM radio broadcasting. The characteristics of MF include a relatively longer wavelength compared to higher frequencies, allowing for groundwave propagation as well as skywave propagation under certain conditions, making it suitable for broadcasting over medium to long distances. In this context, the range of 300 kHz to 3,000 kHz encompasses the frequencies that are utilized for various maritime, aeronautical, and broadcasting communication systems. This fundamental understanding of frequency ranges is essential for anyone working in radio communication systems. Other ranges listed do not correspond to Medium Frequency. The range from 3 – 30 MHz typically refers to High Frequency (HF), while 30 – 300 MHz is classified as Ultra High Frequency (UHF). The range 30 – 300 kHz does not fall within the commonly accepted frequency division for MF either.
