How is frequency measured?

Frequency measures how often an event occurs in a specified period, particularly in the context of waves and oscillations. It is quantified as the number of cycles or events that happen in one second. The standard unit for frequency is Hertz (Hz), which is defined as one cycle per second. This makes it the appropriate choice for measuring frequency, distinguishing it from other physical quantities that may use different units.

For instance, meters are a unit of length, Joules represent energy, and Newtons measure force, which are unrelated to the concept of frequency. Therefore, knowing that frequency is specifically represented in Hertz clarifies its role in physics, especially in fields dealing with waves, like sound and electromagnetic radiation.
