Periodicity is the quality of occurring at regular intervals or periods (in time or space) and can occur in different contexts:

In timing devices:

  • A clock marks time at periodic intervals.
  • A metronome ticks at periodic intervals of time.

In science:

  • Periodicity in time is often specified by its frequency which has the metric units of Hertz (the number of periods per second).
  • Oscillations, waves and standing waves have crests at periodic intervals of space and/or time.
  • 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.
  • In mathematics, a periodic function is a function whose output contains values that repeat periodically.
  • In mathematics, in group theory, a periodic group is a group in which each element has finite order.
  • In chemistry, the periodic table is a table which classifies the chemical elements by means of the periodicity of their chemical properties.
  • In physics, the ability of a magnet to swing/settle

Other uses:

  • In finance, the periodicity of a loan describes the interval between payments.
  • A publication published at periodic intervals can be called a "periodical", for example a magazine.
  • In music theory, periodicity is described as "predictability gives rise to expectations".
