Path of a ray of light passing through three liquids of reflective indices mu_(1), mu_(2), mu_(3) is as shown in Fig. Which liquid has the smallest index of reflection ?

A ray of light passes through four transparent media with refractive indices mu_1 , mu_2 , mu_3 and mu_4 as shown in the figure. The surfaces of all media are parallel. If the emergent ray CD is parallel to the incident ray AB, we must have
