Question

with respect to air the refractive index of a flint glass and alcohol is 1.6 and 1.3 respectively. the refractive index of the flint glass with respect to alcohol is​

Answer 1

Given:

$\displaystyle \mu_g$ = 1.6

$\displaystyle \mu_a$ = 1.3

To find:

$\displaystyle ^g\mu _a$ =?

Explanation:

We know that the refractive index of medium 1 wrt medium 2 is the ratio of

refractive index of medium to refractive index of medium 2.

So refractive index of the flint glass with respect to alcohol is​

  $\displaystyle ^g\mu _a = \frac{\mu_g}{\mu_a}$

  $\displaystyle ^g\mu _a = \frac{1.6}{1.3}$

$\displaystyle \mathbf{^g\mu _a = 1. 23}$

Hence the refractive index of the flint glass with respect to alcohol is​ 1.23
