Question

If the refractive index of a medium increases then what is the velocity of light passing through it?​

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.
