The absolute refractive index of a medium (nm) is given by the formula

Question
The absolute refractive index of a medium (nm) is given by the formula
nm = speed of light in the medium / speed of light in air
nm = speed of light in air / speed of light in the medium
nm = speed of light in air x speed of light in the medium
nm = speed of light in the medium squared
Answer
nm = speed of light in air / speed of light in the medium
Detailed Explanation
The chapter gives the absolute refractive index formula as nm = c/v = speed of light in air divided by speed of light in the medium.
