A) \[\theta \]
B) More than \[\theta \]
C) Less than \[\theta \]
D) \[\frac{\theta {{\lambda }_{1}}}{{{\lambda }_{2}}}\]
Correct Answer: C
Solution :
Critical angle = \[{{\sin }^{-1}}\left( \frac{1}{\mu } \right)\] \\[\theta ={{\sin }^{-1}}\left( \frac{1}{{{\mu }_{{{\lambda }_{1}}}}} \right)\] and \[\theta '={{\sin }^{-1}}\left( \frac{1}{{{\mu }_{{{\lambda }_{2}}}}} \right)\] Since \[{{\mu }_{{{\lambda }_{2}}}}>{{\mu }_{{{\lambda }_{1}}}}\], hence \[\theta '<\theta \]You need to login to perform this action.
