2 answerConsider a solution to the wave equation $ psileft(x,tright) $, then using Fourier transform, we can represent: $ psileft(x,tright)=left(frac{1}{2pi}right)^{2}int_{-infty}^{infty}int_{-infty}^{infty}widetilde{psi}left(k,omegaright)e^{ileft(kx+wtright)}dkdw $ Now if we'll apply this form into the...
