Question

how is the refractive index of medium related to the speed of light in these two media​

Answer 1

Answer:

Let v1 be the speed of light in medium 1 and v2 be the speed of light in medium 2. The refractive index of medium 2 with respect to medium 1 is given by the ratio of the speed of light in medium 1 and the speed of light in medium 2. This is usually represented by the symbol n21.

Answer 2

We know that

$\sf The \: refractive \: index \: of \: the \: media \: is \\ \sf given \: n_m$

$\sf \: n_m = \frac{ \large \: Speed \: of \: light \: in \: air }{ \large \: Speed \: of \: light \: in \: medium}$

Let , v¹ the speed of light in medium 1 and v² be the speed of light in medium 2 .

The refractive index of medium 2 with respect to medium 1 is usually represented by the symbol .

$\tt \: n_{21} = \frac{ \large \: Speed \: of \: light \: in \: medium \: 1 }{\large \: Speed \: of \: light \: in \: medium \: 2} = \frac{v {}^{1} }{v {}^{2} }$
