How do you solve a wave equation using Fourier transform? Taking the Fourier transform, we find: F(Ψ(x,t=0))=δ(x−2). The Fourier transform is 1 where k = 2 and 0 otherwise. We see that over time, the amplitude of this wave oscillates with cos(2 v t). The solution to the wave equation for these initial conditions is therefore Ψ(x,t)=sin(2x)cos(2vt) . 8 Nov 2022
