Superposition Principle

Be sure the simulation has finished loading before you begin.


Click on the problem number to initialize the simulation. Answer the question after you have run the simulation. You may click and drag inside the animation to read the coordinates (position is given in meters and time is given in seconds) in order to obtain numerical values for use in your equations. Enter your function and click on the button to test your answers.

  • Postlab 1
    Find a wave function, g(x,t), that will produce a standing wave with a node at x=0, (i.e., at the center.)
  • Postlab 2
    What wave function, g(x,t), will produce a beat wave with a beat frequency of 0.2 Hz.

Test your function here. g(x,t)=
