Question

Define absolute refractive index and
relative refractive index. Explain in brief
with an illustration for each.​

Answer 1

Answer:

The absolute refractive index is defined as the ratio of the speed of light in vacuum and in the given medium. The absolute refractive index should never be less than 1.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.relative index of refraction

: the ratio of the velocity of light in two different media.
