Frequency

Frequency refers to the number of occurrences of a repeating event per unit of time. It is a fundamental concept in various fields such as physics, engineering, and statistics. In the context of waves, such as sound waves or electromagnetic waves, frequency is the number of times a wave's cycle repeats in one second. The unit of frequency is the Hertz (Hz), where one Hertz is equivalent to one cycle per second.

In physics, frequency is crucial for understanding phenomena like resonance and wave propagation. For example, the frequency of a sound wave determines its pitch, with higher frequencies corresponding to higher pitches. In the electromagnetic spectrum, different frequencies correspond to different types of radiation, from radio waves at the low-frequency end to gamma rays at the high-frequency end.

In statistics, frequency can refer to how often a particular data point or range of data points occurs within a dataset. This is often visualized using frequency distributions, histograms, or bar charts. Understanding
