find refractive index of water with respect to alcohol

Answer 1

 Refractive index of medium 1 with respect to medium 2 (2µ1) It is given that: With respect to air, refractive index of water is 1.33. With respect to air, refractive index of benzene is 1.50. Therefore, with respect to water, refractive index of benzene == 1.127

Answer 2

The correct answer to the question is 0.978.

CALCULATION;

As per the question, we are asked to calculate the refractive index of water with respect to alcohol.

The refractive index of any medium 2 with respect to medium 1 is calculated as -

                             $\mu_{2}^1=\frac{\mu_{2}} { \mu_{1}}$

Here, $\mu_{2}$  is the refractive index of medium 2 with respect to air

         $\mu_{1}$ is the refrcative index of the medium 1 with respect to air

The refractive index of the water with respect to air is $\mu_{w}$ = 1.33

The refractive index of the alcohol with respect to air is $\mu_{a}$ = 1.36  

Here, we have taken a common value of refractive index of alcohol with respect to air.

Hence, the refractive index of water with respect to alcohol is calculated as-

                          $\mu_{w}^a\ =\ \frac{\mu_{w}} {\mu_{a}}$

                                 = $\frac{1.33}{1.36}$

                                 = 0.978    [ans}
