What unit of measure is used to describe frequency?

Frequency is measured in Hertz (Hz), which quantifies the number of cycles of a periodic phenomenon that occur in one second. The term was named after Heinrich Hertz, a physicist who made significant contributions to the study of electromagnetic waves. In this context, one Hertz signifies one complete cycle per second. This measurement is critical in various fields, including telecommunications, audio engineering, and networking, as it defines the rate at which signals oscillate and is fundamental for understanding bandwidth, data transmission, and signal processing.

Watts, decibels, and amperes measure different electrical properties: watts assess power, decibels express logarithmic ratios of sound intensity or power levels, and amperes quantify electrical current. These units serve distinct purposes and are not appropriate for representing frequency. Thus, Hertz is the correct and specific unit of measure for frequency.
