Fresnel equations
How carefully did you check this edit to Fresnel equations? If you just compared with an equation in a book and found that they disagreed, you have probably made a mistake. The equations depend on a sign convention, which is arbitrary and is chosen differently by different authors. I don't have my reference books here so I can't check it until tomorrow, but if you didn't consider that edit very carefully please reverse it for now, until you have time to check the math and the sign conventions.--Srleffler 14:42, 29 May 2006 (UTC)
