Tíðni
Tíðni is the Icelandic word for frequency, used across science and everyday language to describe how often something occurs within a given context. In physics and engineering, it refers to the number of complete cycles of a periodic phenomenon per unit time.
Measured in hertz (Hz), frequency f is the reciprocal of the period T (f = 1/T). The angular
In statistics, tíðni describes how often a value appears in a dataset. Absolute frequency is a simple
Beyond physics and statistics, tíðni appears in genetics as allele frequency, indicating how common a genetic
Overall, tíðni conveys the concept of rate or occurrence across disciplines, from the cadence of a waveform
