Question

The refractive index of glass with respect to water is (9)/(8). while that of turpentine with respect to water is (10)/(9). The refractive index of glass with respect to turpentine is

Answer 1

Answer:

the speef of light is invrsly propotional to refractive index

water travels faster as compared to truptine ball bcz the refractive index of water is lower than than truptine ball

mark me as a brainlist

Answer 2

Answer:

81/80

Explanation:

$_{w} n_{g}$ = 9/8

$_{w} n_{turpentine}$ = 10/9

⇒ $_{turpentine} n_{g}$ = $\frac{1}{\frac{10}{9}}$  ×  $\frac{9}{8}$  = $\frac{81}{80}$
