A) \[0{}^\circ \]
B) \[30{}^\circ \]
C) \[60{}^\circ \]
D) \[90{}^\circ \]
Correct Answer: A
Solution :
Angle of prism \[A=30{}^\circ \] Incident angle \[i=60{}^\circ \] Deviation angle\[\delta =30{}^\circ \] \[\delta =e+i-A\] \[e=A+\delta -i\] \[=30{}^\circ +30{}^\circ -60{}^\circ \] \[e=0\]You need to login to perform this action.
