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. WebThis is because the concentration of the solution in each tube is directly proportional to its optical density, and as the concentration increases, the amount of light absorbed by the solution increases, leading to a higher optical density reading. Therefore, when we plot the optical density values against the known concentration values, we ...
