White Light Colours through Crossed Polarisers

Supporting pages are an introduction to birefringence and a statement of the problem (.doc file).

This applet was written to show how colours are created when white light passes through crossed polarisers with a birefringent plate in between. The birefringent plate has its optic axis perpendicular to its thickness.

 The applet and web pages were designed and coded by Gary Skinner, from an intital idea by Sylvanus P Thompson, as part of his undergraduate physics project.
