A) 30°
B) 45°
C) 60°
D) 75°
Correct Answer: B
Solution :
\[i\propto \tan \theta \Rightarrow \frac{{{i}_{1}}}{{{i}_{2}}}=\frac{\tan {{\theta }_{1}}}{\tan {{\theta }_{2}}}\Rightarrow \frac{\sqrt{3}}{3}=\frac{\tan {{30}^{o}}}{\tan {{\theta }_{2}}}\Rightarrow \theta ={{45}^{o}}\]You need to login to perform this action.
