When looking through a prism, the image is displaced in which direction?

When looking through a prism, the image is displaced toward the apex. This phenomenon occurs due to the refraction of light as it passes through the prism's angled surfaces. When light enters the prism, it bends toward the base, but this results in an apparent shift of the image toward the apex.

In a triangular prism, the apex is the point where the two sides meet, and the base is the opposite side. The bending of light at the prism's surfaces causes objects viewed through the prism to appear displaced from their original position. This is critical for understanding visual perception when prisms are used in various optical applications, such as correcting vision or in optical instruments.

Other options would imply displacement in the wrong direction, misunderstanding the basic principles of light behavior in prisms. Focused awareness of how prisms manipulate light is essential in both clinical and practical scenarios in ophthalmic practice.
