Draw the diagram given below and clearly show the path taken by the emergent ray.

An object is viewed through a glass prism with its vertex pointing upwards. It appears to be displaced upward. Explain the reason.
Four students A, B, C and D traced the paths of incident ray and the emergent ray by fixing pins P and Q for incident ray and pins R and S for emergent ray for a ray of light passing through a glass slab.
