Hi Jonny (or anyone else that might know)

I have an index of refraction of 1.356.

The question I need to know is what would the index of refraction be at minus 40 degrees Celsius between air and ice and air and water (I believe it could be water at the right atmospheric pressure)

Also if possible what would be the index of refraction be between nitrogen and water and oxygen and water.

Or any combination of these elements that would yield 1.356 index of refraction. Whiskey gives us the correct value but I find it difficult to believe that the builders at Giza left us the index of refraction of whiskey in the middle of The Giza Plateau. Carbonated beverages yields the correct value also but I don't think pop was meant either.

Thanks in advance for anyone who can help.

Don Barone

PS: Temperature correction

Refractive index is a function of temperature, not least because of density changes in condensed materials with changes in T. A simple correction can be applied in most circumstances to allow you to report a value in the standard way: at a temperature of 25�C.
