FREQUENCY Meaning and
Definition
-
Frequency refers to the rate at which something occurs or repeats over a specific period of time. In physics, frequency is associated with the number of cycles or oscillations that occur in a given interval. It is commonly expressed in hertz (Hz), which represents the number of cycles per second. For instance, if a wave completes 10 cycles in one second, it has a frequency of 10 Hz.
In the field of statistics, frequency represents the number of times a specific event or particular value occurs within a data set. It is often expressed as a count or a proportion. For example, when conducting a survey, the frequency of a certain response would indicate the number of respondents who chose that specific option.
In telecommunications and signal processing, frequency refers to the number of times a signal or wave repeats within a given time period. It plays a crucial role in determining the bandwidth and encoding of various forms of communication signals, such as radio waves, sound waves, and digital signals.
Frequency is also used in everyday language, particularly to describe how often something happens or how regularly an event occurs. It can be synonymous with terms like regularity, recurrence, or repetition. For example, the frequency of daily bus arrivals would describe how often the buses come.
