Question

DEFINE REFRACTIVE INDEX​

Answer 1

Answer:

$\huge\pink{\boxed{\green{\mathfrak{\overbrace{\underbrace{\fcolorbox{red}{aqua}{\underline{\pink{❂Radhe Radhe❂}}}}}}}}}$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 2

Answer:

It is a value calculated from the ratio of speed of light in a vaccum to that second medium of greater density

FORMULA: n=c/v

where n= refractive index

c= speed of light

v= phase velocity of light
