Frequency (Other)
Frequency measures the number of recurring events per unit of time in periodic phenomena such as waves, oscillations, and rotations. In the International System of Units (SI), the fundamental unit of frequency is the hertz (Hz), defined as one cycle per second. Frequency is inversely proportional to period, representing how rapidly a cyclic state repeats. Related measures include angular velocity, expressed in radians per second, and rotational speed.
