A ray traveling through a large vat filled with medium 1 , index of refraction \(n_{1}=1.3\), is incident on a flat layer (thickness \(d=12 \mathrm{~mm}\) ) of medium 2, index of refraction \(n_{2}=1.6\). If the light enters medium 2 at an angle \(\theta_{1}=40^{\circ}\) with respect to the normal to the interface between the media, how far is it shifted from its original path once it exits medium 2?
