Which term denotes a frequency equal to one thousand cycles per second?

Which term denotes a frequency equal to one thousand cycles per second?

• A. Kilohertz
• B. Hertz
• C. Megahertz
• D. Nanohertz

Answer: (A)

Frequency describes how many cycles occur each second, and the basic unit is hertz. The prefix kilo- means thousand, so when you have 1,000 cycles per second, that is called kilohertz. In other terms, 1 kilohertz equals 1,000 hertz. For context, one hertz is one cycle per second, megahertz is a million cycles per second, and nanohertz is one-billionth of a hertz. So the term for 1,000 cycles per second is kilohertz.
