Description:

Physics educational software for high school and college students and teachers. Study the interference of two circular waves.It is often hard to obtain good results with a ripple tank. Interference is a good supplement.

Features:

Change source separation, phases and wavelength.
Show displacement or intensity.
Show path lengths and phases of the waves in an arbitrary point.
Make and view animations of the rolling wave pattern.
Five activities included which may be modified or you may create your own.

System requirements:

Windows 95/98/Me/NT/2000/XP. Also works on a Mac PC emulator.
Pentium processor (at least 200 MHz recommended).
32 MB RAM.
16 bit color or better.

The pictures show (click to enlarge):

An intensity pattern and the intensity along a horizontal line.
A 3D interference pattern.
A screen shot with 4 simulations, an open activity and the generation of an animation.
