Refractive index of milk

WebThe Refractive Index - n - of a medium is a measure for how much the velocity of light is reduced inside the medium. The velocity of light in a medium can be expressed as v = c / n (1) where v = velocity of light in the medium (m/s, ft/s) c = speed of light in air or vacuum - approximately 3 108 m/s (or 299792458 m/s) n = refractive index WebThe refractive index of denser medium 1 with respect to rarer medium 2 will be n 12 = 1/sin i c. Some typical critical angles are listed in Table 9.1. ... Add a few drops of milk or any other suspension to water and stir so that water becomes a little turbid. Take a laser pointer and shine its beam through the turbid water.
