Frequency

f=\dfrac{1}{T}

Result unit: Hz (hertz, 1/s)

What it describes

The number of full oscillations (cycles) per second — the reciprocal of the period.

f

frequency

[Hz]

T

period

[s]

Frequency and period are two sides of the same coin — the shorter the period, the more oscillations per second.

Oscillations and waves; converting between period and frequency.

An oscillation has a period of 0.25 s. Calculate the frequency.

Substitution

T=0.25

Result

f=\dfrac{1}{0.25}=4

Hz.
