Detailed Solution

Refractive index of the medium B relative to medium A is

\frac{\sqrt 3}{\sqrt 2}

.
As we know, the formula for the refractive index is given by

n = \frac{sin i}{sin r}

where

n

is the refractive index,

i

is the angle of incident, and

r

is the angle of refraction

\Rightarrow n = \frac{\sin 60 °}{\sin 45 °}

\Rightarrow n = \frac{(\sqrt 3 / 2)}{(1 / \sqrt 2)}

\Rightarrow n = \frac{\sqrt 3}{\sqrt 2}
