Question

With respect to air, the refractive indices of water and benzene are 1.33 and 1.50 respectively. Calculate the refractive index of benzene with respect to water.

Answer 1

refractive index of water is 1.33 and benzene is 1.50
: refractive index of benzene w.r.t to water = 1.50/1.33
= 1.13

Answer 2

Answer:

The refractive index of benzene with respect to water is 1.127.

Explanation:

We will use the following equation to solve this question,

$\mu_b_w=\frac{\mu_b}{\mu_w}$             (1)

Where,

$\mu_b_w$=relative refractive index of benzene with respect to water

$\mu_b$=refractive index of benzene

$\mu_w$=refractive index of water

From the question we have,

$\mu_w$=1.33

$\mu_b$=1.50

By putting the value of μw and μb in equation (1) we get;

$\mu_b_w=\frac{1.50}{1.33}$

$\mu_b_w=1.127$

Hence, the refractive index of benzene with respect to water is 1.127.
