The following applet shows the superposotion of two waves.
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 checkboxsame V to select the first one.

Cyan curve is the sum of the above two waves.

  • Please feel free to post your ideas about how to use the simulation for better teaching and learning.
  • Post questions to be asked to help students to think, to explore.
  • Upload worksheets as attached files to share with more users.
Let's work together. We can help more users understand physics conceptually and enjoy the fun of learning physics!
