Q-00106568
What is the relationship between the refractive index and the speed of light in a medium?
1
Higher refractive index means faster light speed
2
Lower refractive index means slower light speed
3
Higher refractive index means slower light speed
4
Refractive index has no effect on light speed
Answer and Solution
Answer
C. Higher refractive index means slower light speed
Solution:
A higher refractive index indicates that light travels slower in that medium compared to a vacuum, while a lower refractive index indicates a higher speed of light. Thus, the correct answer is that higher refractive index means slower light speed.
