Question

explain Relative Refractive Index​

Answer 1

Answer:

The ratio of the speed of light in a vacuum to the speed of monochromatic light in the substance of interest. Also called the absolute index of refraction it is commonly called the refractive index or index of refraction. ... That ratio should be called a relative refractive index.

Answer 2

$\mathtt{ \huge{\fbox{Answer :)}}}$

The ratio of speed of light in vacuum to the speed of light in medium is lcalled " relative refractive Index "

Relative refractive Index have no SI unit , then obviously it is dimensionless quantity

It is denoted by the letter " n "

A high refractive index indicates that light moves slowly through the medium
