The amplitude of a wave is the maximum displacement of the particle of the medium from its equilibrium position. Check this page to know the formula for Amplitude with Solved Example.
A time-domain progressive wave equation is derived from the usual linear acoustic wave equation, and it is shown that the solution to this new equation can be expressed as a Feynman path integral. This path integral representation is used to derive the time-dependent statistics of acoustic ...
The approximate value of the wave velocity υ down the tube is (71)v=c1−σtλ/2πa If the tube wall were perfectly rigid, then the tube impedance would be infinite (σt → 0) and the velocity would be c. The attenuation is given by the factor eiκtx/a. If the tube were ...

by Webster, any practical horn is too short to load an acoustic source, so the performance is virtually the same as letting the source radiate into free‐space; but the horn does notattenuate the progressive wave below the ''cutoff'' frequency in the same way that high‐order modes are ...
An inverse source problem for the heat equation is considered. Extraction formulae for information about the time and location of when and where the unknown source of the equation first appeared are given from a single lateral boundary measurement. New roles of the plane progressive wave solutions...
Mathematically, the evolution of the magnetization vector M can be described by a vector differential equation named after Felix Bloch: dM/dt = γ(M × Beff) − (Mxx + Myy) / T2 − (Mz − M0)z / T1, where the operator × denotes the vector cross product; γ is the ...
A wave travelling along the x-axis is described by the equation v(x, t) = 0.005 cos(alpha x - betat). If the wavelength and the time period of the wave are 0.
Visualization of the strain wave front of a progressive acoustic wave based on the Talbot effect How to visualize a strain wave front of a progressive acoustic wave by means of conventional Fresnel imaging is shown. The theory suggests that for a Raman... N Saiga,Y Ichioka - 《Applied Optics...
In this Chapter, we also address thedynamical interpretationof Landau damping. In Section 5.11 we study a nonlinear theory of Vlasov–Poisson system for a restricted wave form called BGK (Bernstein–Greene–Kruskal)wave. The BGK wave is restricted in the sense that it is a progressive wave ...
