A) \[>41{}^\circ \]
B) \[<41{}^\circ \]
C) \[=41{}^\circ \]
D) \[\ge 41{}^\circ \]
Correct Answer: B
Solution :
Given \[A=60{}^\circ \] \[e=46{}^\circ \Rightarrow i=55{}^\circ \] Since, \[i+e=A+\delta \] \[\Rightarrow \] \[55+46=60+\delta \] \[\Rightarrow \] \[\delta =41{}^\circ \] Practically the angle of minimum deviation for a glass prism is less than\[40{}^\circ \](about\[38{}^\circ \]or\[39{}^\circ \]) So, \[\delta <41{}^\circ \]You need to login to perform this action.
