## Definition

It is the quantity that quantifies the number of occurrences of the same event during a certain period of time (cycles, turns, oscillations, etc.).

In the area of circuits and energy, we have the electrical frequency, which determines the oscillations per second in the alternating electrical current. We also have the sound frequency, statistical frequency, which follow the same pattern as the electric one, that is, it is the number of cycles or events that occur in a unit of time.

The International System of Units (SI), uses the rotation per second as standard, the hertz (Hs) was defined to represent the frequency measurement unit. There are other units of measurement, including: MHz (megahertz), GHz (gigahertz), cps (cycles per second), rpm (revolutions per minute), BPM (beats per minute), among others.

### Formula

Period and frequency are related quantities, therefore, for the calculation of the frequency or period of a wave or body, we need to divide the numeral 1 by the period (the frequency is obtained) or the numeral 1 by the frequency (we obtain if the period), note below:

#### f = 1 / T

#### T = 1 / f

#####
Note that:

f: frequency

T: period

Period is the quantity that quantifies the time necessary for a body or wave to complete an occurrence (cycle, turn, rotation) around a point. The unit of measurement used is the second (s).

### Origin of the term Hertz

The hertz is a tribute to Heinrich Rudolf Hertz, who was a German physicist who lived between 1857 and 1894, he played an important role in the area of electromagnetic radiation. It was defined that an object performing a circular movement with a frequency of 60 Hz, for example, completes 60 revolutions every second. Or a wave vibrating at 60 Hz means that it oscillates 60 times per second.
