A) \[{{\sin }^{-1}}\left( \frac{4}{5} \right)\]
B) \[{{\sin }^{-1}}\left( \frac{5}{4} \right)\]
C) \[{{\sin }^{-1}}\left( \frac{1}{2} \right)\]
D) \[{{\sin }^{-1}}\left( \frac{2}{1} \right)\]
Correct Answer: A
Solution :
\[\mu =\frac{{{\mu }_{1}}}{{{\mu }_{2}}}=\frac{5/3}{4/3}=\frac{5}{4}\] \[\sin C=\frac{1}{\mu }=\frac{4}{5}\] \[C={{\sin }^{-1}}\left( \frac{4}{5} \right)\]You need to login to perform this action.
