The following applet shows the superposotion of two waves./htdocs/ntnujava/ejsuser/2/users/ntnu/fkh/wavesuperposition_pkg/wavesuperposition.propertiesFull screen applet or Problem viewing java?Add http://www.phy.ntnu.edu.tw/ to exception site list
Blue curve represent wave move in x direction: y(t)=A*sin(k*x-w*t);
where k=wavelength/(2*pi), w=period/(2*pi)
Green curve represent wave move in +x or -x direction: y(t)=A*sin(k*x-w*t+phi) or y(t)=A2*sin(k*x+w*t+phi) :Click checkbox[b]same V[/b] to select the first one.
Cyan curve is the sum of the above two waves.
