In prism terminology, if light is displaced toward the apex, toward which part is the image displaced?

Explanation:
When light passes through a triangular prism, it undergoes two refractions that shift the path sideways. If the ray is displaced toward the apex, the net effect is that the apparent source of the light (the image) moves toward the opposite side of the prism—the base. This results from tracing the emergent rays back to where they would converge; their backward extension places the image on the base side. So the image is displaced toward the base.
