Since the prism is larger at the base base it slows light down longer than the pinnacle, and light changes course down towards the base as it exits the prism. If the contact were equally dense through the duration of, it'd slow the light down but the route would remain unchanged. The amount of course change depends upon the index of refraction of the product set alongside the index of refraction of air.
