Question
Which is equal to 3.525 MHz?
Answer Options
- A) 0.003525 kHz
- B) 35.25 kHz
- C) 3525 kHz
- D) 3,525,000 kHz
Correct Answer: C
Explanation
The prefix ‘mega-’ (\text{M}) means 1,000,000, and ‘kilo-’ (\text{k}) means 1,000. Therefore, one megahertz (\text{MHz}) is equal to 1,000 kilohertz (\text{kHz}).
To convert 3.525\text{ MHz} to \text{kHz}, you multiply by 1,000: 3.525\text{ MHz} \times 1000\text{ kHz/MHz} = 3525\text{ kHz}. This frequency is located in the 80-meter amateur band.
