Question

Define refractive index

Answer 1

✨ hey , here is ur answer ✨

REFRACTIVE INDEX ⤵⤵

it is the extend of change of directions of light in a given pair of media .
the refractive index is a relative value of speed of light in the given pair of media
thus , to calculate the refractive index the speed of two media is taken .
