define relative refractive index of medium
Answers
Define relative refractive index ?
ANSWER :
When we measure speed of light in two different media, relative refractive index of medium 2 with respect to medium 1 is defined as the ratio of speed of light in medium 1 to speed of light in medium 2.

Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another. ... Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or n = c/v.
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
