Quizplus · Accepted Answer

The index of refraction is defined as the ratio of the speed of light in a vacuum to the speed of light in a given medium. The higher the value of the index of refraction, the more the light is slowed down as it travels through the medium. Therefore, the greatest possible value for the index of refraction is the medium that slows down light the most, which is D with a value of 2.4.
