What effect does a prism have on an image?

Enlarge the image
Displace the image towards the apex
Invert the image
Reduce the image's size

The correct answer is: Displace the image towards the apex

A prism has a unique optical property that alters the path of light as it passes through it. When light enters a prism, it is bent or refracted due to the change in medium, which causes the image to shift or be displaced. This displacement occurs towards the apex of the prism, the point where the two refracting surfaces meet. Because of how light is directed through the prism, the image appears to move in the direction of the prism’s apex. This phenomenon is particularly important in optics and can play a significant role in the correction of various visual disorders in areas such as optometry and ophthalmology. Understanding this effect is crucial for opticians, as it helps in designing lenses and prisms for visual aids that cater to specific patient needs. The other options describe effects like enlargement, inversion, or reduction in size that do not accurately represent the primary function of a prism, which is to displace images rather than alter their dimension or orientation in those specific ways.
