4. a. Find the solution of the one-dimensional wave equation J²u მ2 J²u მე:2 by introducing a change of variables from (x, t) to two moving coordinates (ε,n), one moving to the left (with velocity -c) and one moving the right (with velocity c): xct and n = x+ct b. Show that c² in the one-dimensional equation has the dimensions of velocity squared.
