Question

what is significance of refractive index​

Answer 1

$\huge \boxed{hey \: there}$

➡The refractive index is a measure of the speed of light in that medium.

➡ The refractive index of a medium gives an indication of the light bending ability of that particular medium.

➡ It is expressed as the ratio of the sine of angle of incidence to the sine of the angle of refraction.

➡It is constant for pure substances under standard conditions.
