How much will one diopter prism deviate a ray of light in a distance of one centimeter?

Apex
One meter
Base
One diopter prism

The correct answer is: One diopter prism

A Apex is not a unit of measurement and is not related to optics. B: One meter is a unit of length and does not describe the deviation of a ray of light. C: Base refers to one of the sides of a diopter prism and does not provide information about the deviation of light. Therefore, the correct answer is D, as a one diopter prism will deviate a ray of light by one centimeter in a distance of one centimeter. This is because a diopter measures the curvature of a lens, and a one diopter lens will bend the light by an angle of one centimeter over a distance of one centimeter.
