Just say to to the unreal “Standard Refraction” argument. There is a law -Snell’s law which has been proven and proven again with ACTUAL experimentation. No theory. Adding a refractive index to automatically make objects RISE is a fallacy. It FAILS the scientific examination on both issues: Angle of incidence and change of medium. LETS STOP REFERENCING STUFF WITH NO BASIS IN FACT. Link to calculator: http://www.endmemo.com/physics/snells.php
