Caustic (optics)
I undid your edit to Caustic (optics). You seem to have reverted to an older version of the article, or perhaps pasted in an old version from your sandbox. That version has too many problems, including ones that you have fixed yourself since then. Quite aside from content, it includes a lot of typography problems and nonproductive changes to the article's wikicode. --Srleffler (talk) 18:41, 27 January 2020 (UTC)
