Amplitude is something that relates to the maximum displacement of the waves. Furthermore, in this topic, you will learn about the amplitude, amplitude formula, formula’s derivation, and solved example.
In addition to amplitude, frequency, and period, their wavelength and wave velocity also characterize waves. The wavelength λ λ is the distance between adjacent identical parts of a wave, parallel to the direction of propagation.
A wave’s amplitude is the maximum distance (positive or negative) a wave reaches from its rest position. Wavelength is the distance between the same spot on two sections of a wave. A wave’s frequency can be measured by how many crests (or how many troughs) pass a location in a certain amount of time.
Amplitude Formula. The amplitude of a wave is the maximum displacement of the particle of the medium from its equilibrium position. It is represented by A. The Amplitude formula can be written as. \ (\begin {array} {l}y=Asin (\omega t+\phi )\end {array} \)
The wave equation is a second-order linear partial differential equation for the description of waves or standing wave fields such as mechanical waves (e.g. water waves, sound waves and seismic waves) or electromagnetic waves (including light waves).
Waves are propagating or moving from one region to another one. During this, waves carry energy in their motion. So, a wave is a disturbance on a medium or in a vacuum too with wavelength, velocity, and frequency. This article will explain the waves physics formulas with examples.
Amplitude refers to the maximum change of a variable from its mean value. The amplitude formula helps in determining the sine and cosine functions. Amplitude is represented by A. In a periodic function with a bounded range, the amplitude is half the distance between the minimum and maximum values.
