In what unit is frequency measured?

• A. In Hertz (Hz), which represents the number of cycles per second.
• B. In Watts, which represents power.
• C. In meters per second, which represents velocity.
• D. In decibels, which represents gain.

Answer: (A)

Frequency is how many times something repeats in one second. The unit that expresses this rate is the Hertz (Hz), which literally means cycles per second. For example, 1 kHz equals 1000 cycles per second, 1 MHz equals 1,000,000 cycles per second, and so on. The other units don’t measure repetition rate: Watts measures power, meters per second measures speed, and decibels express a logarithmic ratio of quantities like level or gain rather than frequency.
