Answers. Best Answer: Oil, but the difference is not huge: (Oil: refractive index is about 1.5. Water has a refractive index of about 1.3). But the reason is not easy to explain. Oil slows light down more than water, but that is not quite an explanation.A table of various refractive indices can be found here: http://www.robinwood.com/Catalog/Technic...Very roughly speaking, one could say that there is more interaction between the molecules in oil and the light, than with water and light.ut the reason is not easy to explain.
