this statement?

Answers

Answered by aadeeti2006

Answer:

the ratio between the speed of light in medium to speed in a vacuum is the refractive index.

If we say that the refractive index of diamond is 2.42, it means that the ratio of the speed of light in air and the speed of light in diamond is 2.42. Since, the refractive index of diamond is quite high, it means that the speed of light in diamond is very low.
