Hey
I am currently looking into refractometry, and how light reflects off a interface between to materials. I have looked through most of the other threads but nothing really explained what I am looking for.
My problem, I have a digital refractometer and I am measuring the reflective angle of plant sap through its internal glass prism. However, plant sap contains a water-surcose solution, with free compounds like protiens, minerals, cellulose etc. Because of this I am not sure if my refractometer index readings are a function of the water-soluble content (water, surcose, fructans) or the water-soluable and structural content (+ the proteins minerals etc.).
If the incident light is in a perfect material, say glass, and hits a second material which has many different types of compounds and atoms in it, what happens to the reflected light and its angle?
I notice that you should treat the material as a whole structure when photons hit it. But if this material has many different atoms, molecules and structures at this interface you can't apply this simple rule.
Thanks in advance and any ideas would be greatly appreciated.
Cheers
Toby
