Q. A ray incident at $15{^\circ}$ on one refracting surface of a prism of angle $60{^\circ}$, suffers a deviation of $55{^\circ}$. What is the angle of emergence
A) $95{^\circ}$
B) $45{^\circ}$
C) $30{^\circ}$
D) None of these
Explanation
(d) Using $\delta = i_{1} + i_{2} - A \Rightarrow 55 = 15 + i_{2} - 60 \Rightarrow i_{2} = 100{^\circ}$
