A) \[{{\sin }^{-1}}\frac{1}{\sqrt{3}}\]
B) \[{{\cos }^{-1}}\sqrt{3}\]
C) \[{{\sin }^{-1}}\sqrt{3}\]
D) \[{{\tan }^{-1}}\sqrt{3}\]
Correct Answer: A
Solution :
[a] \[\mu =\tan {{i}_{p}}=\tan {{60}^{o}}=\sqrt{3}\] \[\sin {{i}_{C}}=\frac{1}{\mu }=\frac{1}{\sqrt{3}}\Rightarrow {{i}_{C}}={{\sin }^{-1}}\frac{1}{\sqrt{3}}\]
