What is the unit used to measure the frequency of a wave?

Explanation:
The frequency of a wave is how many times the wave repeats in one second. The unit for this is the Hertz (Hz). One Hertz equals one cycle per second, so if a wave has a frequency of 5 Hz, it completes five cycles each second. Hertz is the SI unit for frequency (often written as s^-1). The other units listed—Newton (force), Meter (length), and Watt (power)—measure different physical quantities, not how often a wave repeats. In practice, frequencies can also appear as kilohertz, megahertz, or gigahertz for higher-frequency waves.
