Web6 Nov 2015 · y (x, t) = f (x + ct) + g (x − ct). This is the general solution of the wave equation; in o the r words, all solutions can be written as a sum of a leftward travelling wave and a rightward travelling wave. Now, the wave on our string can’t travel forever, because the ends of the string are fixed: y (0, t) = 0 = y (l, t) for all t.
