An ice cube has a bubble inside. When viewed from one side the apparent distance of the bubble is \(12 \mathrm{~cm}\). when viewed from the opposite side, the apparent distance of the bubble is observed as \(4 \mathrm{~cm}\). If the side of the ice cube is \(24 \mathrm{~cm}\), the refractive index of the ice cube is;
