Two and multiple-beam interference
This program compares two and six beams interference using phasors. The idea is that this should be illustrating the origin of the different interference patterns, and in particular the reasons why multiple-beam interference gives so much sharper peaks than two-beam interference. If you double click on the graph then all lines are drawn double thickness. This gives the application increased visibility on a data projector. This application was written by Dr Aly Gillies at the University of St Andrews.
