How is the frequency of a wave measured?

The frequency of a wave is measured in hertz (Hz), which quantifies how many cycles or oscillations occur in one second. This unit is derived from the definition of frequency, which is the number of complete waves that pass a given point in a specific period of time. A wave with a frequency of 1 Hz means that one complete wave cycle occurs in one second. This measurement is fundamental in various fields of science, including physics, engineering, and telecommunications, as it helps describe properties of waves, such as sound and electromagnetic radiation.

Other units mentioned, such as kilograms, seconds, and meters, do not relate to frequency. Kilograms measure mass, seconds measure time, and meters measure distance. Each of these has its relevance in scientific contexts, but they do not pertain to how often a wave oscillates, which is specifically captured by the hertz measurement.
