A) \[\mu >1.33\]
B) \[\mu >1.4\]
C) \[\mu >1.5\]
D) \[\mu >1.25\]
Correct Answer: B
Solution :
Condition for TIR \[\operatorname{i}\ge C\] \[Sin\operatorname{i}\ge \operatorname{Sin}\operatorname{C}\] ?(1) \[\operatorname{Sin}\operatorname{C}=\frac{1}{\mu }\] use the equation (1) \[\operatorname{Sin}\,\,i\ge \frac{1}{\mu }\] \[\mu \ge \sqrt{2}\Rightarrow \mu \ge 1.412\]You need to login to perform this action.
