Problem
Medium X has absolute refractive index 1.33 and medium Y has absolute refractive index 1.52.
A third medium Z is such that the relative refractive index of Z with respect to Y is 54.
(i) Calculate the relative refractive index of Y with respect to X, nYX, and that of X with respect to Y, nXY.
(ii) Show that nYXnXY=1 for the pair of media X and Y.
(iii) Determine the absolute refractive index of medium Z.
(iv) Arrange the three media X, Y and Z in ascending order of optical density, giving a brief reason for your choice.
