Define frequency: Frequency

frequency, in physics, the number of waves that pass a fixed point in unit time; also, the number of cycles or vibrations undergone during one unit of time by a body in periodic motion. FREQUENCY definition: 1. the number of times something happens within a particular period, or the fact of something…. Learn more. In the realm of physics and engineering, understanding the concepts of frequency, wavelength, and period is crucial. These fundamental properties describe various aspects of waves, from sound waves to electromagnetic radiation. This article aims to delve into the definitions of frequency, wavelength, and period, as well as explore their interrelationships. For cyclical phenomena such as oscillations, waves, or for examples of simple harmonic motion, the term frequency is defined as the number of cycles or repetitions per unit of time. The conventional symbol for frequency is f or ν (the Greek letter nu) is also used. [3] .
