what does the index of refraction directly measure?\no the angle between the incident ray and the normal line\no the angle between the refracted ray and the normal line\no the bending of light in a medium\no the reflection of light in a medium
Answer
Brief Explanations:
The index of refraction is a measure of how much light bends as it passes through a medium. It is defined as the ratio of the speed of light in a vacuum to the speed of light in the medium. The greater the index of refraction, the more the light bends.
Answer:
the bending of light in a medium
