• 11:38, 28 May 2022 Rainald62 talk contribs reverted File:Phase diagram of water simplified.svg to an old version (Reverted to version as of 22:28, 21 February 2021 (UTC) Vapour and Gas are not mutually exclusive. The dotted line is inappropriate (as is the sudden change green↔brown to the right of the critical point). Restoring also proper margins.)

• 18:19, 27 September 2020 Rainald62 talk contribs uploaded a new version of File:Lens5.svg (Caustic is visible only with more rays. Transparent rays add up to darker color. Rays calculated according to Snell's Law (obviously not in previous versions). Caveats: 1. Even with transparency, there is a saturation effect underemphasizing the intensity in the focus. 2. This is a 2-D calculation (section through a cylindrical lens).)
