Sorry I'm confused about what form of boundary conditions should take.
Why do we need here condition Ux=vt but not Ux=0? If x = vt means "location of the wave is its velocity times t" then why don't we use Ux=ct boundary condition for cases without v mentioned? Shouldn't c be the velocity? If we have v, what is c?
Could someone or professor please explain? Thanks!
