A) \[\text{4}{{\text{5}}^{\text{o}}}\text{,}\,\frac{1}{\sqrt{2}}\]
B) \[{{30}^{\text{o}}}\text{,}\,\sqrt{2}\]
C) \[{{45}^{\text{o}}}\text{,}\,\sqrt{2}\]
D) \[{{30}^{\text{o}}}\text{,}\,\frac{1}{\sqrt{2}}\]
Correct Answer: B
Solution :
\[i={{45}^{0}};\,A={{60}^{o}};\,{{\delta }_{m}}=2i\,-A={{30}^{o}}\] \[\mu =\frac{\sin \left( \frac{A+{{\delta }_{m}}}{2} \right)}{\operatorname{sinA}/2}=\frac{\sin {{45}^{o}}}{\sin {{30}^{o}}}=\frac{1}{\sqrt{2}}.\frac{2}{1}=\sqrt{2}\]You need to login to perform this action.
