What does the bending of light as it passes from a medium of lesser density to a medium of greater density refer to?

One diopter prism
Refraction
All colors
Electromagnetic Theory

The correct answer is: Refraction

Refraction refers to the bending of light as it passes from a medium of lesser density to a medium of greater density. This phenomenon occurs due to the change in speed of light as it moves from one medium to another. The other options, such as A and D, are unrelated to the process of refraction and are not applicable in this context. Additionally, the statement "all colors" in option C is too general and does not accurately describe the specific phenomenon being referenced in the question.
