Find the value of the angle of emergence from the prism. Refractive index of the glass is $\sqrt{3}$ .

Answer:

Solution:

No refraction at face AC.

Apply Snell's law at face BC,

we get,

$μ_{1} \sin i = μ_{2} \sin r$

$\sqrt{3} \sin 30 ° = 1 \times \sin (e)$

$\frac{\sqrt{3}}{2} = \sin (e)$

$\Rightarrow e = 60 °$
