A wave is represented by the equation y=10sin2π(100t−0.02x)+10sin2π(100+0.02x). The maximum amplitude and loop length are respectively View Solution Q2 y =15sin (660t – 0.02x) can be used to calculate the equation of a progressive wave. The wave...
vv –Wave velocity; λλ –Wavelength; AA –Amplitude; and ϕϕ –Initial phase of the wave. Harmonic wave: an example of calculations Let's assume that you want to find out what the wavelength of a certain wave is. You have measured its displacement at two points, both at time t...
Based on the true amplitude one‐way wave equations and the surface boundary condition corrections, we have developed true amplitude common‐shot migration and have proved that it produces an inversion output that agrees asymptotically to Kirchhoff inversion. In the next step, we propose a way to ...
The equation for an axisymmetric wave propagating in a rigid circular duct or pipe is as follows: pr,z=pm0J0αomr/aeiγomz−ωt pmo is the amplitude of the pressure wave, r is the radial distance from the center of the pipe to any point, a is the radius of the pipe, z is the...
Also, this equation is a typical first-order hyperbolic equation in (x,t) being viewed to describe a wave of amplitude u propagating with a wave speed a. 11.2.3.1 Consistency We choose a central difference formula for the discretization of the space derivative ux and a forward difference ...
of DSR preserved-amplitude wave field continuation formulae in a condition of high-frequence hypothesis.The theoretic analysis and models on synthetic datasets show that the proposed method not only can focus scattering energy,turn over to the correct position and improve the imaging fidelity,but ...
With respect to seismic data gathered at the Chilean continental margin, a conventional processing flow to obtain seismic records with a high signal-to-noise ratio is introduced. Then, the imaging results of the conventional and amplitude-preserved one-way wave equation migration methods based on ...
The flow, unsteady heat release and inlet boundary conditions are set to the same as in the analytical models. Unlike the analytical models, the effect of choked outlet is involved in LEE method automatically in the numerical solving process [72,89]. We can find that the only difference ...
Since we have Gauss's theorem, which is always satisfied for a moving charge, the flux enclosed area dS is kept constant when we follow the “flux pipe” as shown in Fig. 1a. Thus Sign in to download full-size image Fig. 1. Electric field lines of moving charge, and spherical wave-...
