Frequency

Definition:

Frequency refers to the number of occurrences of an event or phenomenon within a given time period. It is a fundamental concept in various fields, including physics, statistics, and telecommunications.

Physics:

In physics, frequency is a measure of how often a periodic motion or oscillation repeats in a given unit of time. It is typically measured in hertz (Hz), where one hertz represents one cycle per second. The frequency of a wave or vibration determines its pitch in the case of sound waves or the color in the case of light waves.

Statistics:

In statistics, frequency represents the count or tally of observations falling into a particular category or interval. It is commonly used to construct frequency distributions, histograms, and other graphical representations to understand the distribution of data.

Telecommunications:

In telecommunications, frequency refers to the range of electromagnetic wave frequencies used for transmitting information. Different frequency bands are allocated for various purposes, such as radio broadcasting, mobile communication, and satellite communication.
