Solution

The correct option is D 90 $^{\circ}$
$μ \times s i n 45 = s i n r \times 1$
$\sqrt{2} \times \frac{1}{\sqrt{2}} = s i n r$

$\Rightarrow r = 90^{\circ}$

Light falls at normal incidence on one face of a glass prism of refractive index √2. Then the angle of emergence when the angle of the prism is 45∘

The correct option is D 90∘μ×sin45=sinr×1√2×1√2=sinr⇒r=90∘

Light falls at normal incidence on one face of a glass prism of refractive index $\sqrt{2}$ . Then the angle of emergence when the angle of the prism is 45 $^{\circ}$

The correct option is D 90 $^{\circ}$
$μ \times s i n 45 = s i n r \times 1$
$\sqrt{2} \times \frac{1}{\sqrt{2}} = s i n r$

$\Rightarrow r = 90^{\circ}$
