We know ,

From snells law ,

➝Sin i = n sin r

➝Sin 60° = √3 Sin r

➝ √3/2 = √3 Sin r (sin 60°= √3/2 )

➝ Sin r = 1/2 .

➜ $\boxed{r = 30° }$

Angle of deviation ,

$\implies \: \delta \: = i - r \\ \\ \implies \: 60 - 30 \\ \\ = 30 \degree \: . \: \: \\ \\ \\ \implies \: \boxed{ \delta \: = 30 \degree} \\ \\$
