(CBSE 2011, 2012) Or Define absolute refractive index of a medium. We observed that simultaneously quantitative information about the refractive index and absorption of milk, as a function of fat concentration, could be obtained with both devices. Milk teeth are important because they ... Did you know the name “milk” teeth comes from the fact that the refractive index of milk teeth is similar to that of milk? density and refractive index measurements can be made is limited by the relatively low solubility of lactose and by the readiness with which super saturated solutions tend to deposit crystals. addition. 2003 Mar;57(3):288-92. doi: 10.1366/000370203321558191. The refractive index of milk samples was measured with a reflectometer. Moreover, it helps to differentiate between different fats, such as butter and margarine. Sign-up for the latest news. Added skim milk or removal of fat is detected by the lowered values of refractive constant, which in average samples is reduced below the minimum for pure milk at about a minimum of 20–25 per cent. Correspondence to We obtain the refractive indices of enamel, dentin, and cementum to be 1.631+/-0.007, 1.540+/-0.013, and 1.582+/-0.010, respectively. Agr. The Refractive Index - n - of a medium is a measure for how much the velocity of light is reduced inside the medium. -U.S. Dept. Find the refractive index of glass such that the angle of refraction is 19.5°. Root resorption of deciduous teeth .
