A) 1.8
B) 1.5
C) 1.6
D) 1.7
Correct Answer: B
Solution :
\[i={{35}^{o}},\delta ={{40}^{o}},e={{79}^{o}}\] \[\delta =i+e-A\] \[{{40}^{o}}={{35}^{o}}+{{79}^{o}}-A\] \[A={{74}^{o}}\]and\[{{r}_{1}}+{{r}_{2}}=A={{74}^{o}}\] solving these, we get \[\mu =\text{1}.\text{5}\] \[\mu <\frac{\sin \left( \frac{74+40}{2} \right)}{\sin 37}\]\[{{\mu }_{\max }}=1.44\]You need to login to perform this action.
