A) \[{{\sin }^{-1}}\left( \frac{4}{3} \right)\]
B) \[{{\tan }^{-1}}\left( \frac{4}{3} \right)\]
C) \[{{\sin }^{-1}}\left( \frac{4}{3} \right)\]
D) \[{{90}^{0}}\]
Correct Answer: C
Solution :
In this situation, semivertex angle = critical angle \[{{i}_{C}}\] \[={{\sin }^{-1}}\left( \frac{1}{\mu } \right)\] \[={{\sin }^{-1}}\left( \frac{3}{4} \right)\]You need to login to perform this action.
