6.2 A solution consists of solute molecules 1 dissolved in a liquid medium 2, where the refractive indices of 1 and 2 are n=1.45 and n2 = 1.50. The solution is brought into contact with another liquid 3 that is completely immiscible with 2. It is found that most of the solute molecules 1 transfer from medium 2 into medium 3. What is the refractive index ng of medium 3? Assume that only dispersion forces are operating Repeat the analysis for the case where n1 = 1.50 and n2 = 1.45. (Hint: It is not enough to calculate the change in the solute's dispersion self-energy on either side of the 2-3 interface; one must also establish that the solute is attracted from one side and repelled from the other. Answer: 1.45 <13< 1.50 in both cases.)
