What is true about the index of refraction?
A) if light rays are taken up by the object then it has a high index of refraction
B) it measures the frequency of the light as it reflects from a material
C) oil immersion lenses increase the problem of refraction
D) light will bend as it passes through two substances with different indices of refraction

Question

Quizplus · Accepted Answer

The index of refraction is a measure of how much a substance can bend light, and light will bend as it passes through two substances with different indices of refraction. Option A is incorrect because a high index of refraction means that light is slowed down and bent more, not taken up. Option B is incorrect because the index of refraction does not measure frequency. Option C is incorrect because oil immersion lenses actually reduce problems with refraction by matching the refractive index of the glass and the oil.
