Question

How is the refractive index of an optical medium related to the speed of light in that medium?​

Answer 1

Answer:

The refractive index of a medium (n) is equal to the speed of light (c) divided by the velocity of light through the medium (v). Rearranging the equation allows us to see the relationship regarding v. The lower the refractive index, the faster the velocity of light. Medium A has the smaller refractive index
