Frequency of a wave

One of the important characteristics of any wave is its frequency, the number of oscillations per unit of time. The most common unit used internationally to express the frequency of a wave is the hertz, symbolized by Hz, which is equivalent to one oscillation per second. Thus, for example, to say that a violin string, placed in vibration by the musician, emits a sound wave of 440 Hz frequency (reads 440 hertz), means that this sound wave produced by the instrument performs 440 oscillations every second. .
