Hertz is defined as what?

Explanation:
Hertz measures how many cycles occur per second, so it is the unit of frequency. One hertz equals one cycle per second (s^-1). It differs from units of speed (meters per second), wavelength (meters), or impedance (ohms), which describe different physical quantities. In ultrasound, frequency refers to how rapidly the wave oscillates each second, and Hertz precisely quantifies that rate.
