But there was some experiment which light bends in curved path in a solution of varying concentration from top to bottom. So there was a gradient of optical density(higher at bottom) and caused smooth curving of light Edit: Oh it was just sugar solution http://physicsed.buffalostate.edu/pubs/StudentIndepStudy/EURP09/Sugar/sugar.html Edit 2: Found this too which is much better demo https://m.youtube.com/watch?v=rnNjV3fh-4M permalink fedilink source parent
