Question

with respect to air the refractive indices of water and benzene are 1.33 and 1.55 respectively. calculate the refractive index of benzene with respect o water.

Answer 1

$$\begin{gathered} \mathrm{Refractive}\mathrm{index}\mathrm{of}\mathrm{benzene}\mathrm{wrt}\mathrm{water}=\frac{\mathrm{Refractive}\mathrm{index}\mathrm{of}\mathrm{benzene}}{\mathrm{Refractive}\mathrm{index}\mathrm{of}\mathrm{water}} \\ =\frac{1.55}{1.33} \\ =1.17 \end{gathered}$$
