Interference Demonstration

Physics Area: Optics

Topics Covered: Interference

Interference effects can be demonstrated using a simulated ripple tank.  

Click on the forward button after the frames have been calculated to start the animation.


Wavelength:

 


Enter values for a new source:

x position:
y position:
amp[0..1]:
phase in degrees:

 

The location of the sources can be changed by click-dragging on the source in the applet.

New Sources can be added and the wavelength changed by imputing values in the boxes to the side of the applet.

The "edit" button at the bottom of the applet can also be used to add sources.  In edit mode, position can be changed by click-dragging.
