Frequency is measured in what unit?

Frequency refers to the number of cycles of a periodic wave that occur in a given unit of time. In the International System of Units (SI), frequency is measured in hertz (Hz). One hertz is defined as one cycle per second, making it a direct measurement of how rapidly an event occurs over a time period.

Decibels are used to express the intensity of sound; pascals are a unit of pressure; and watts measure power. While all of these are important in particular contexts, they do not measure frequency. Understanding the appropriate units for different physical quantities is crucial, as each unit relates specifically to a unique aspect of measurement in fields such as physics and engineering.
