Q. Find the value of the angle of emergence from the prism. Refractive index of the glass is $3$ .

$6 0^{\circ}$

$3 0^{\circ}$

$4 5^{\circ}$

$9 0^{\circ}$

$< b r / > < b r / > r_{1} + r_{2} = A = 3 0^{\circ} < b r / > r_{2} = 3 0^{\circ} (r_{1} = 0^{\circ}) < b r / > < b r / >$
From Snell's law,
$3 sin r_{2} = 1 x$ sine
$< b r / > < b r / > 3 sin 3 0^{\circ} = sine < b r / > e = 6 0^{\circ} < b r / > < b r / >$
