Weband we obtain the wave equation for an inhomogeneous medium, ρ·u tt = k ·u xx +k x ·u x. When the elasticity k is constant, this reduces to usual two term wave equation u tt = c2u xx where the velocity c = p k/ρ varies for changing density. 1.3 One way wave equations In the one dimensional wave equation, when c is a constant, it is ... Webinhomogeneous boundary condition so instead of being zero on the boundary, u(or @u=@n) will be required to equal a given function on the boundary. The second kind is a \source" or \forcing" term in the equation itself (we usually say \source term" for the heat equation and \forcing term" with the wave equation), so we’d have u t= r2u+ Q(x;t)
