Question about refractive index
«

Hi,
I don't have any background in chemistry - except for some basic chemistry from elementary..
Is there a way to engineer a liquid with a specific refractive index ?
If yes, how? and if not, why?
Thanks,
Zvi

Well, dissolving something in water will shift it's refractive index. The question is, what liquid do you have, what's it's refractive index, and where do you want to shift it to?

Hey, I'm not judging. I just like to shoot straight. I'm a man of science.

Dear
zviman
;
I think not for a pure liquid as you think because
there is no relationship
between structure (chemical compound) and specific refractive index (SRI).
But you may be able to do/design it in some ranges with mixtures of miscible solvents, or solve some "transparent" compound in such a Solvent.
I think also that it needs some empiricism to find the correct mass ratio.
I hope I have given you at least a possible Idea.
Good Luck!

Thank you both for your response
After doing a little web search, I realized that the refractive index is also affected by the density of the liquid - and I didn't find any liquid compound that has a refractive index more then 1.8
For example, Silicon has a refractive index of 4 - is there a way to engineer a liquid in a room temp with the exact refractive index, or is it impossible to engineer such a liquid because liquids are lesser density than solids?

Dear
zviman
;
If I consult the following Table, then I have very hard to believe that there will be any liquid with a refractive index higher than 2.0:

But you may ask also:
