Question

write an expression to relate absolute refractive index of a medium . show that refractive index is inversely proportional to the velocity in the medium​

Answer 1

Answer:

Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or n = c/v. refractive indexDiagram of a light ray being refracted.

Answer 2

Answer:

An incandescent light bulb is shown through a glass prism. The certain wavlength of the light is then directed into a glass cuvette containing an unknown concentration of protein. Commonly, this process is called spectroscopy and is used to determine the concentrations of DNA, RNA, and proteins in solutions. The indices of reflection of air, glass, and the solution are 1, 1.5, and 1.3, respectively.
