Learn what frequency is and how it is measured in Hertz. Explore the two types of frequency: angular and spatial, with examples and formulas. 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 is a fundamental concept in science, engineering, and everyday life. It describes how often a particular event or pattern occurs over a specific period. Frequency plays a key role in fields such as physics, electronics, telecommunications, and even music. Parameters of a Wave Frequency definition states that it is the number of complete cycles of waves passing a point in unit time. The time period is the time taken by a complete cycle of the wave to pass a point. Angular frequency is angular displacement of any element of the wave per unit of time. Consider the graph shown below. It represents the displacement y of any element for a harmonic wave along a string moving in the positive x-direction with respect to time. Here, the string element ...
