While performing the experiment to trace the path of a ray of light passing through a glass prism, four students marked the incident ray and the emergent ray in their diagrams in the manner shown below. The correct path of the rays has been shown by:?

The solution requires the diagrams that were shown to the students. Without the diagrams, it's impossible to determine which path is correct. The correct path would show the ray of light bending towards the normal as it enters the denser medium (glass) and away from the normal as it exits the denser medium into air. The amount of bending depends on the angle of incidence and the refractive indices of air and glass.
