MCQ

Mark the correct answer in the  question.

If the refractive index of glass with respect to air is 3/2, what is the refractive index of air with respect to glass?

#### Options

•  $\frac{1}{2}$

• 3

• $\frac{1}{3}$

•  $\frac{2}{3}$

#### Solution

${}{a}{\mu}_g = \frac{\mu_g}{\mu_a} = \frac{3}{2}$

where,

${}{a}{\mu}_g = \text{ Refractive index of glass w . r . t . air }$

$\mu_g =\text{ Refractive index of glass }$

$\mu_a = \text{ Refractive index of air }$

Thus,

${}{g}{\mu}_a = \frac{\mu_a}{\mu_g} = \frac{2}{3}$
where,

${}{g}{\mu}_a = \text{ Refractive index of air w . r . t . glass }$
