In this lecture, an initial boundary value problem for the wave equation is solved, i.e., the wave equation is posed on a finite interval in space and boundary conditions are specified at the two endpoints. The method of reflection is exposed.

On Slides 38, 39, 40, second order derivatives of Psi (at the points 0 and l ) appear. This is an error, Please replace these second order derivatives of Psi with second order derivatives of Phi (at the points 0 and l ).
