Question

The refractive index of glass with respect to air is 1.5. What will be the refractive index of air with respect to glass?

Answer 1

Answer:

0.67

Explanation:

$refractive \: index \: = \alpha$

${ \alpha }^{g \: to \: a} \: = 1.5$

${ \alpha }^{a \: to \: g} = \frac{1}{ { \alpha }^{g \: to \: a} }$

${ \alpha }^{a \: to \: g} = \frac{1}{1.5}$

${ \alpha }^{a \: to \: g} = 0.67$
