A diagram showing three horizontal layers of liquids stacked vertically: Liquid 1 at the top, Liquid 2 in the middle, and Liquid 3 at the bottom. A dashed vertical line extends down through all three layers representing the normal line. A light ray enters Liquid 1 from above traveling down and right, making angle theta_1 with the normal. At the first horizontal boundary, the ray enters Liquid 2 and bends closer to the normal, making a smaller angle theta_2. At the second horizontal boundary, the ray enters Liquid 3 and bends sharply away from the normal, making a larger angle theta_3. No other labels, lines, text, or axes appear.
Light ray traversing three immiscible liquid layers.
A continuous ray of light passes through three transparent, immiscible liquids stacked in horizontal layers labeled Liquid 1, Liquid 2, and Liquid 3 from top to bottom. The angles that the light ray makes with the normal to the boundaries in each liquid are \(\theta_1\), \(\theta_2\), and \(\theta_3\), respectively, where \(\theta_2 < \theta_1 < \theta_3\). Which of the following correctly ranks the indices of refraction \(n_1\), \(n_2\), and \(n_3\) of the three liquids?
