Question

Relationship between speed of light and refractive index

Answer 1

Answer: Refractive index (n) = Speed of light (c) / Velocity of light in the medium (v)

Explanation: n = Refractive index of a medium

c = speed of light

v = velocity of light through the medium

n = c / v ; Higher the Refractive index, slower the velocity of light in the medium.

Lower the Refractive index, faster the velocity of light in the medium.
