Question
Which is equal to 1,500,000 hertz?
Answer Options
- A) 1500 kHz
- B) 1500 MHz
- C) 15 GHz
- D) 150 kHz
Correct Answer: A
Explanation
This is another standard unit conversion problem. The prefix ‘kilo-’ (\text{k}) means 1,000. Therefore, one kilohertz (\text{kHz}) is equal to 1,000 hertz (\text{Hz}).
To convert 1,500,000\text{ Hz} to \text{kHz}, you divide by 1,000: 1,500,000\text{ Hz} / 1000\text{ Hz/kHz} = 1500\text{ kHz}. This frequency is in the Medium Frequency (MF) radio range, a common band for commercial broadcast AM radio.
