The following applet shows the superposotion of two waves.
Red curve represent wave move in x direction: y(t)=A*sin(k*x-w*t);
where k=wavelength/(2*pi),  w=period/(2*pi)
Cyan curve represent wave move in +x or -x direction: y(t)=A*sin(k*x-w*t+phi) or y(t)=A*sin(k*x+w*t+phi) :Click checkbox [b]same V[/b] to select the first one.
Pink curve is the sum of the above two waves.
