Phasor Addition Calculator -- Ph213
See: http://en.wikipedia.org/wiki/Phasors and http://en.wikipedia.org/wiki/Diffraction
Click on the link below to run the program, which allows you to change a number of parameters, such as how many phasors are passing through how many openings in an opaque screen. The output of the program includes:
* how the multiple waves (each shown as a 'ray') are pointing towards a distant screen;
* the phasors for each wave, as well as the resultant phasor they produce when added together;
* the intensity pattern for the resulting interference pattern produced on the distance screen.
