Quizplus · Accepted Answer

Magnification is determined by the ratio of the image distance to the object distance. When light travels slower in a medium, such as glass, it bends more, resulting in a larger angle of incidence and therefore greater refraction. This results in a larger image distance and a smaller object distance, which leads to greater magnification. Therefore, light traveling slower in glass would result in greater magnification than if it were to propagate instantaneously, travel faster in glass, or spread out more.
