A) \[15{}^\circ \]
B) \[30{}^\circ \]
C) \[45{}^\circ \]
D) \[60{}^\circ \]
Correct Answer: C
Solution :
Given: angle of prism \[A=60{}^\circ \] , minimum deviation \[{{\delta }_{m}}=\] \[30{}^\circ \] \[\therefore \]Angle of incidence \[i=\frac{A+{{\delta }_{m}}}{2}\] \[=\frac{60{}^\circ +30{}^\circ }{2}=45{}^\circ \]You need to login to perform this action.
