Frequency is measured in hertz (Hz). Hertz is the unit of measurement for frequency, and it represents the number of cycles per second of a periodic signal, such as a sound wave or an electromagnetic wave.
One hertz is equivalent to one cycle per second. For example, if a sound wave completes 440 cycles in one second, its frequency is 440 Hz. Hertz can also be used to measure the frequency of other periodic events, such as the rotation of a motor or the vibration of a string.
Meter per second is the unit of measurement for speed or velocity. Seconds are units of time, and farad is the unit of measurement for capacitance.
