Periodicity is the quality of occurring at regular intervals or periods (in
timeor space) and can occur in different contexts:
clockmarks time at periodic intervals.
metronometicks at periodic intervals of time.
* A publication published at periodic intervals can be called a "periodical", for example a
* In mathematics, a function whose output contains values that repeat periodically is called a
* In chemistry, the
periodic tableis a table which classifies the chemical elements by means of the periodicity of their chemical properties.
* In physics, period is the number of cycles as a result of time (time/cycle). The amount of time it takes to complete one full revolution. Period is also the inverse of frequency.
music theory, periodicity is described as "predictability gives rise to expectations".
Standing wavescrest at periodic intervals of distance.
finance, the periodicity of a loan describes the interval between payments.
* The measure of periodicity in time is
frequencywhich has the metric units of Hertz.
