I hypothesised the refractive index will increase as the concentration of sugar in the water increases. Abstract. The liquid water is what causes the refraction alongside with the glass container. Odds are that the paper filter does not have uniform 2 micron pores, so its efficacy in this application is questionable. 6. The refractive index is increasing because the solution is getting #thicker# creating a denser medium with a higher refractive index. The bending of light when it travels from one medium to another is known as refraction. It might be at a few hundred ppm, but its still orders of magnitude less than the sugar or alcohol content (parts per hundred) that actually affect the … Physics - HL. As solids are dissolved in a beaker of water, light will increasingly bend as the concentration increases. The index of refraction for 80% sugar solution is known to be about 1.5, while water is 1.33. solution concentration and refractive index has many applications such as measuring sea salt concentration [3] and beer quality assessment [4]. Measurements of solution concentration, optical rotation, and refractive index are physical quantities that are often measured in physical experiments. This is not magic but it is a property of light known as refraction. How does sugar concentration affect the refractive index of water IA?

How does the sugar concentration affect the refractive index of water? How does salt concentration affect the refractive index of water? In the process of replacing water molecules in 1.0 concentration 3M the interstitial fluid with glucose molecules, we observed the increase of optical transmission, i.e., the 0 3 6 9 12 15 18 DM transparency, which is due to the matching of Time, min refractive indices of the interstitial fluid and the collagen fibres. After that there is weak dependence of con centration of refractive index. How does sugar effect the refractive index of a water solution; what is their relationship? If the molarity of sugar water is increased by a constant amount 0.2 M, then the calculated index of refraction will show a similar linear increase. Abstract. 5. Research Question: What is the effect of salt on the refractive index of water. Hypothesis: The refractive index of the tap water will be higher than that of the salt water. To find how salinity effects the refractive index of the water I constructed a system which is as follows: I conducted this experiment by using a clear glass container in the shape of a rectangular prism, 400ml beaker, measuring spoons, light box, protractor, ruler, pencil (to mark points), paper (to draw the rays on), water and sugar.
