A) \[i=45{}^\circ ,\text{ }e=50{}^\circ \]
B) \[i=30{}^\circ ,\text{ }e=45{}^\circ \]
C) \[i=45{}^\circ ,\text{ }e=45{}^\circ \]
D) \[i=30{}^\circ ,\text{ }e=30{}^\circ \]
Correct Answer: C
Solution :
In the position of minimum deviation, the angle of incidence is given by \[=\frac{A+\delta m}{2}\] \[=\frac{60+30}{2}={{45}^{o}}\] and angle of emergence = angle of incidence \[={{45}^{o}}\]You need to login to perform this action.
